Doc Text:
A flaw was found in GitPython. A remote attacker with low privileges can exploit a vulnerability in the `TagReference.create()` function, where a positional reference parameter bypasses a security guard. This allows the attacker to supply a specially crafted reference value, such as `--file=<path>`, to read arbitrary files on the system. The contents of these files are then returned within the annotated tag message, leading to information disclosure.

Description OSIDB Bzimport 2026-08-25 01:53:12 UTC 
GitPython before 3.1.59 contains an arbitrary file read vulnerability in TagReference.create() where a positional reference parameter bypasses the unsafe option guard. Attackers can supply a reference value like --file=<path> to read arbitrary files, with contents returned in the annotated tag message.
