Lifecycle Timeline
3DescriptionCVE.org
A vulnerability was identified in Aider-AI Aider 0.86.3. Affected is an unknown function of the file aider/args.py of the component Pre-commit Hook Handler. Such manipulation of the argument git-commit-verify leads to protection mechanism failure. The attack may be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Protection mechanism failure in Aider-AI Aider 0.86.3 exposes git pre-commit hook bypass via manipulation of the git-commit-verify argument in aider/args.py, allowing authenticated remote attackers to commit code without triggering pre-commit security controls. The CVSS temporal score includes E:P (proof-of-concept exploit publicly available, linked to GitHub issue #5057), and the vendor has not yet responded to the responsible disclosure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated access at a low privilege level (PR:L per CVSS vector) - unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.3 (Medium) reflects AV:N (network-reachable), AC:L (low complexity), PR:L (low privileges required), UI:N (no user interaction), with partial C/I/A impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege access to an Aider-integrated development environment - such as a shared coding server, developer workstation, or Aider web UI - crafts or influences the `git-commit-verify` argument passed to the Pre-commit Hook Handler in `aider/args.py`. By setting this argument to bypass verification, all configured pre-commit hooks (secret scanners, linters, policy gates) are skipped, allowing the attacker to commit code containing embedded secrets, backdoors, or policy-violating content without detection. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
