Job Search Tailor

• Outcome: Review
• Latest audit: Sep 16, 2026 · 8:19 AM UTC
• Version: 0.1.1

Overview

The skill has a coherent job-search purpose, but it should be reviewed because it persists resume-derived data and lets untrusted job pages and configurable paths influence local file writes.

Install only if you are comfortable storing resume-derived files and job history locally under ~/.job-search. Review config.json paths before running, keep Google Docs disabled unless you deliberately set up credentials later, and manually approve any newly created archetype or resume file before relying on it.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

• Location: SKILL.md:151
• Finding: Untrusted Job-Page Content Is Processed Without Prompt-Injection Isolation<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md`, lines 151–170 **Vulnerability Type**: Indirect prompt injection through externally controlled job descriptions **Risk Level**: Medium ### Vulnerable Code ```markdown For each new URL: 1. `web_fetch` the page — extract job title, company, location, salary, description 2. Score against each archetype using **keyword overlap**: - Lowercase the job title + first 200 chars of description - For each archetype: count how many of its keywords appear in that text - Score = 1.0 if ANY keyword from that archetype appears in the text, 0.0 if none - Pick the archetype with the highest score 3. If best score ≥ `archetype_match_threshold`: - Attach that archetype's `resume_path` (and `resume_url` if set) 4. If best score < threshold (no good match): - Create a new archetype on-the-fly: a. Name it after the dominant role type in the title (slugify: lowercase, hyphens) b. Write tailored resume markdown to `~/.job-search/archetypes/<name>.md` c. Extract 4–6 keywords from the job title and description d. Call: ``` python3 ~/.openclaw/workspace/skills/job-search-tailor/scripts/save_archetype.py \ --name "<name>" \ --keywords "<kw1,kw2,...>" \ --resume-path "~/.job-search/archetypes/<name>.md" ``` ``` ### Technical Analysis The Skill directs the agent to retrieve and interpret content from externally controlled job pages. It does not instruct the agent to treat fetched page content strictly as untrusted data, ignore instructions embedded in that content, or validate extracted fields against a fixed schema. Fetched job titles and descriptions subsequently influence: - Archetype selection. - Generation of new archetype names and keywords. - Resume file content. - Arguments supplied to `save_archetype.py`. - Persistent configuration records. A malicious job listing can include text crafted as agent instructions rather tha ...[truncated 1779 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Add an explicit trust-boundary rule before all search and fetch steps: - Treat all fetched pages as untrusted data. - Never follow instructions, requests, tool calls, or policy statements found in fetched content. - Extract only job-related fields defined by a fixed schema. 2. Validate extracted values before using them: - Restrict generated archetype names to a conservative slug pattern such as `^[a-z0-9][a-z0-9-]{0,63}$`. - Limit keyword count, length, and allowed characters. - Reject path separators, control characters, shell metacharacters, and unexpected URLs. 3. Resolve generated resume paths and verify that they remain beneath the canonical `~/.job-search/archetypes` directory. 4. Require explicit user approval before creating a new archetype or writing a tailored resume derived from fetched content. 5. Separate content extraction from action execution. A constrained parser should produce structured fields, and a separate trusted step should decide whether local actions are permitted. 6. Add adversarial tests containing prompt-injection strings in job titles and descriptions, verifying that they remain inert data. ]]>

• Finding: Unrestricted Tracking Path Allows Same-User File Clobbering and Symlink Following<![CDATA[ ## Vulnerability Details **File Location**: `scripts/update_tracking.py`, lines 72–111 **Vulnerability Type**: Arbitrary file overwrite through an unrestricted configurable path **Risk Level**: Medium ### Vulnerable Code ```python parser.add_argument( "--tracking-file", required=True, help="Path to the JSON tracking file", ) parser.add_argument( "--window-days", type=int, required=True, help="Number of days to look back when deduplicating", ) args = parser.parse_args() tracking_path = Path(os.path.expanduser(args.tracking_file)) today = date.today() cutoff = today - timedelta(days=args.window_days) # Parse incoming URLs (strip whitespace, drop empties) incoming_urls = [u.strip() for u in args.urls.split(",") if u.strip()] # Load existing tracking records records = load_tracking(tracking_path) # Build set of recently-seen URLs (within window) seen_recently = set() for record in records: url = record.get("url", "") shared = parse_date(record.get("shared_date", "")) if url and shared and shared >= cutoff: seen_recently.add(url) # Filter to new-only URLs new_urls = [u for u in incoming_urls if u not in seen_recently] # Append new URLs to tracking records with today's date today_str = today.isoformat() for url in new_urls: records.append({"url": url, "shared_date": today_str}) # Persist updated tracking file try: save_tracking(tracking_path, records) except OSError as e: print(f"Warning: could not save tracking file: {e}", file=sys.stderr) ``` The write helper follows the supplied path directly: ```python def save_tracking(tracking_path: Path, records: list) -> None: """Write tracking records to file, creating parent dirs as needed.""" tracking_path.parent.mkdir(parents=True, exist_ok=True) with tracking_path.open("w", encoding="utf-8") as f: json.dump(records, f, indent=2) ``` ### Technical Analysis The `--tracking-file` argument is accepted as an unrestricted pa ...[truncated 2389 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Restrict tracking files to a dedicated directory: ```python base = Path("~/.job-search/memory").expanduser().resolve() target = Path(args.tracking_file).expanduser().resolve(strict=False) if target.parent != base: raise ValueError("Tracking file must be inside ~/.job-search/memory") ``` If subdirectories are allowed, use `target.is_relative_to(base)` on supported Python versions. 2. Reject symbolic links and non-regular files before reading or writing. Where available, open files with `O_NOFOLLOW`. 3. Create the tracking directory and file with restrictive permissions, such as directory mode `0700` and file mode `0600`. 4. Write updates atomically: - Create a temporary file in the same trusted directory. - Flush and `fsync` it. - Replace the destination with `os.replace`. 5. Do not silently reset malformed tracking files. Return a non-zero exit status and preserve the original content unless the user explicitly authorizes recovery. 6. Validate configuration fields before invoking the script, including path type and location and reasonable bounds for `window_days`. 7. Add tests covering path traversal, absolute paths outside the approved directory, symbolic links, malformed destination files, and attempted overwrites of unrelated files. ]]>

Findings (10)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence
• Finding: The declared description presents a broad job-search and resume-matching skill, with LinkedIn job discovery, deduplication, automatic archetype matching/creation, and onboarding behavior. The supplied code does none of that. It is narrowly scoped to registering or updating an archetype entry in a local configuration file. While archetype storage could be a supporting component of the larger skill, this code chunk’s actual purpose is materially narrower and does not implement the primary declared behavior. Therefore this is a description-behavior mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence
• Finding: The supplied code implements only one narrow support function from the broader description: deduplicating URLs against a tracking file. It does not search LinkedIn, discover jobs, process resumes, cluster archetypes, match jobs to resumes, create new archetypes, or handle first-run setup and preferences. While deduplication is mentioned in the declared purpose, the actual code chunk’s primary behavior is materially narrower than the declared skill, so the description does not accurately represent what this code chunk actually does.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence
• Finding: The declared description presents an end-user automation skill for searching jobs and tailoring resumes. The actual code chunk is a Python unittest file focused on validating three scripts' CLI behavior. From the tests, the underlying covered capabilities appear limited to config loading, URL dedup tracking, and archetype config persistence. Those are supporting pieces of the declared system, but the main promised functionality—searching LinkedIn for jobs, matching jobs to best-fit archetypes, creating archetypes on the fly based on matching, and bootstrapping by asking the user for resume/roles/locations/preferences—is absent from this code chunk. Because the supplied code's primary purpose is materially different and omits the headline capabilities, this is a mismatch.

Lp3

Medium

• Category: MCP Least Privilege
• Confidence: 93% confidence
• Finding: The skill explicitly instructs use of shell commands, file reads, and file writes, but it does not declare any tool scope or permissions boundaries. That makes the skill over-privileged by default and prevents meaningful policy enforcement or user review of sensitive operations such as writing resume data and config files under the home directory.

Vague Triggers

Medium

• Confidence: 95% confidence
• Finding: Broad trigger phrases like "job search" or "find me jobs" can cause unintended activation in normal conversation. Because this skill can read local config, process resume content, and write files, accidental invocation could expose or persist sensitive personal data without clear user intent.

Session Persistence

Medium

• Category: Rogue Agent

Content

For each result URL, `web_fetch` the full page to extract:
- Job title, company, location, salary (if shown), full job description

### A3. Create archetypes

Analyze the user's resume text alongside 3–5 of the fetched job descriptions.
Identify 3–5 natural clusters of role types that appear in the JDs and align with

• Confidence: 88% confidence
• Finding: The skill creates persistent resume archetypes derived from the user's resume and fetched job descriptions, which is a form of session persistence involving sensitive personal and professional data. Persisting transformed resume content across runs expands exposure surface and can retain more inferred information than the user realizes, especially when combined with ongoing tracking files.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The skill stores sensitive resume content, tailored resume variants, configuration, and job-tracking history under the user's home directory, but it does not clearly warn the user beforehand. Resume data often contains PII, employment history, contact details, and other sensitive information, so silent persistence materially increases privacy and data-handling risk.

Session Persistence

Medium

• Category: Rogue Agent

Content

"_comment_archetypes_dir": "Folder where archetype resume markdown files are stored.",
  "archetypes_dir": "~/.job-search/archetypes/",

  "_comment_threshold": "Min keyword match score (0–1) to use an existing archetype. Below this → create new.",
  "archetype_match_threshold": 0.5,

  "_comment_google_docs": "Set true to push new archetypes to Google Docs. Requires OAuth setup.",

• Confidence: 60% confidence
• Finding: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The guide instructs users to place Google service account credentials or OAuth tokens in a predictable local path and describes uploading resume archetypes to Google Docs, but it omits explicit warnings about the sensitivity of those credentials and the privacy implications of document upload and sharing. In a job-search skill that handles resumes and potentially personal data, this can lead users to store secrets insecurely or expose sensitive career information through misconfigured document sharing.

subprocess module call

Medium

• Category: Dangerous Code Execution

Content

def run(script, args, cwd=None):
    """Run a script as a subprocess and return (stdout, stderr, returncode)."""
    result = subprocess.run(
        [sys.executable, script] + args,
        capture_output=True,
        text=True,

• Confidence: 70% confidence
• Finding: subprocess module calls execute external commands. Without careful input validation, this enables command injection.
