- Unbounded Third-Party Dependency Permits Unreviewed Future Releases<![CDATA[ ## Vulnerability Details **File Location**: `requirements.txt:1` **Vulnerability Type**: `T08: Insecure Dependencies` **Risk Level**: Medium **Vulnerable Code:** ```text requests>=2.25.0 ``` ### Technical Analysis The dependency specification defines only a minimum version and allows the package resolver to install any later release of `requests`. As a result, installations are not reproducible, and future dependency versions can be introduced without review. The requirements file also contains no cryptographic hashes to verify the integrity of downloaded artifacts. This does not demonstrate that the current `requests` package is malicious. However, it creates a supply-chain exposure: if a future compatible release or its distribution infrastructure is compromised, a subsequent installation may automatically select and install the affected artifact. ### Attack Path 1. An attacker compromises a future `requests` release, a maintainer account, or the package distribution channel. 2. The attacker publishes a malicious version greater than or equal to `2.25.0`. 3. A user installs the project dependencies without a lockfile, constraints file, or hash enforcement. 4. The package resolver selects the compromised release because it satisfies `requests>=2.25.0`. 5. Malicious code may run during package installation or when `currency_converter.py` imports `requests`. ### Impact Assessment Successful exploitation would execute code with the privileges of the account installing or running the Skill. Depending on those privileges, the attacker could access readable files and environment variables, alter user-accessible data, make unauthorized network requests, or compromise the Skill's runtime environment. The scope is limited by the operating-system permissions and sandbox controls applied to that account. ]]>
- Remediation
- <![CDATA[ ## Remediation Suggestions - Pin `requests` to a specifically reviewed version, for example: ```text requests==<reviewed-version> ``` - Generate and commit a lockfile or fully pinned requirements file that includes all transitive dependencies. - Require cryptographic hashes during installation, such as by using `pip install --require-hashes -r requirements.txt`. - Obtain packages only from an explicitly configured, trusted package index. - Use automated dependency monitoring to identify vulnerable or compromised releases. - Review and deliberately update dependency pins rather than permitting automatic resolution to arbitrary future versions. ]]>
