Vulnerability Details
File Location:
requirements.txt:1-2
Vulnerability Type: Unconstrained dependency resolution
Risk Level: MediumVulnerable Code
text pdfplumber pypdfThe installation documentation also instructs users to resolve these unconstrained dependencies directly:
File Location:
README.md:32-41bash python3 -m pip install -r ~/.openclaw/workspace/skills/uap-release-analyzer/requirements.txtbash python3 -m pip install pdfplumber pypdfTechnical Analysis
Neither dependency has a pinned version or an integrity hash, and the project provides no lock file covering transitive dependencies. Consequently, installation resolves whichever package versions the configured Python package index serves at that time. The installed code can therefore differ from the code present when this skill was audited.
Both dependencies execute within the user's Python process.
pypdfis imported byscripts/inventory.py, whilepdfplumberis imported byscripts/extract_text.py. A compromised upstream release, package-index account, mirror, or transitive dependency could execute arbitrary code when installed or imported.This is a supply-chain hardening deficiency rather than evidence that the currently named packages are malicious.
Attack Path
- An attacker compromises an upstream dependency release, one of its transitive dependencies, or a package source trusted by the victim.
- The attacker publishes a malicious version that still satisfies the unconstrained requirement.
- A user follows the documented
pip installcommand. pipresolves and installs the attacker-controlled release because no version or hash restriction rejects it.- Malicious code executes during installation or when the pipeline imports the dependency.
- The code runs with the privileges of the user invoking
pipor the analysis scripts.

Remediation Suggestions
-
Pin each direct dependency to a reviewed, exact version, for example:
text pdfplumber==<reviewed-version> pypdf==<reviewed-version> -
Generate a fully resolved lock file containing exact versions of all transitive dependencies.
-
Record SHA-256 hashes and require verification during installation:
bash python3 -m pip install --require-hashes -r requirements.txt -
Use a trusted, explicitly configured package index or an internally controlled package mirror.
-
Add automated dependency vulnerability and provenance scanning to the release process.
-
Re-review dependency updates before changing pinned versions, and test document parsing in an isolated environment.
-
Recommend installation and execution in a dedicated virtual environment or sandbox under a non-privileged account.
