CVE-2026-14966
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk22th percentile - higher than 22% of all known CVEs
Summary
The vulnerability in BBOT's unarchive module fails to detect symlinks in zip and 7z archives when their listing carries a DOS-attribute prefix before the unix mode, as produced by legacy p7zip versions. This allows an attacker-controlled symlink to be written into the extraction directory when such an archive is downloaded and extracted during a scan, bypassing the guard.
Risk Assessment
The risk is limited to planting a symlink (its target is not written through) and only affects hosts using legacy p7zip builds, potentially enabling privilege escalation or access to sensitive files.
Recommendation
Update BBOT to the latest version that includes the fix and avoid using legacy p7zip versions on hosts running BBOT.

BBOT's `github_workflows` module could be induced to write a downloaded artifact outside its configured output directory. Its path-containment check did not resolve `..`, so a crafted `CODE_REPOSITORY` URL could traverse out of the intended folder.
- CVE-2025-10282Medium
BBOT's gitlab module could be abused to disclose a GitLab API key to an attacker controlled server with a malicious formatted git URL.

BBOT's git_clone module could be abused to disclose a GitHub API key to an attacker controlled server with a malicious formatted git URL.
Original NVD description (English source)
BBOT's unarchive module rejects archives containing symlink entries before extraction, but for zip and 7z archives it failed to detect symlinks whose listing carries a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. Such an archive, downloaded and extracted during a scan (for example via filedownload), bypassed the guard and caused an attacker-controlled symlink to be written into the extraction directory. The effect is limited to planting the symlink (its target is not written through), and only hosts using such a legacy p7zip build are affected; current mainline 7-Zip is not.
