Path traversal in github_workflows allows writing artifacts outside output directory
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. The write is bounded to two directory levels above the output location and its target is determined by the operator's configuration, not the attacker.
Symlink guard bypass in unarchive module allows planting symlinks during extraction
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.
The postman_download module uses the workspace name field from the Postman API to construct the local directory path without sanitization. If a malicious workspace has a name containing path traversal characters, pathlib resolves the path outside the intended output directory, allowing an attacker to write arbitrary files to the user's system.
Symlink-following arbitrary write via github_workflows module
The github_workflows module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location.
SSRF via unvalidated WWW-Authenticate realm in docker_pull module
The docker_pull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication request to an arbitrary endpoint, potentially leaking authentication tokens.
The unarchive internal module's archive extraction commands perform no code-level validation on extracted file paths, relying entirely on the behavior of external tools (e.g. GNU tar) which varies by platform. While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extraction path traversal was never fixed. On systems with GNU tar < 1.34 (Ubuntu 20.04, Debian Buster, CentOS 7, many Docker base images), a malicious archive can write files outside the intended extraction directory.
Improper Archive Extraction in unarchive Enables RCE
BBOT's unarchive module could be abused by supplying malicious archives files and when extracted can then perform an arbitrary file write, resulting in remote code execution.
