Description

Summary

bbot's gitdumper.py insufficiently sanitises a .git/config file, leading to Remote Code Execution (RCE).

bbot's gitdumper.py can be made to consume a malicious .git/index file, leading to arbitrary file write which can be used to achieve Remote Code Execution (RCE).

Impact

A user who uses bbot to scan a malicious webserver may have arbitrary code executed on their system.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bbot, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update bbot to 2.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-10283 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
