Vulnerability from github – Published: 2026-04-24 20:42 – Updated: 2026-04-24 20:42

Summary

gitverify has improper tag signature verification

Details

gitverify is still a prototype.

Impact

The bug is related to requireSignedTags which is on by default: an unsigned annotated tag would pass the verification. The commit pointed to by the tag would still have to be signed by a maintainer or a contributor.

Patches

Since the initial commit, fixed in c2c60da05d5c73621d0ce7ea02770bacd79ec8b1 (no semantic versions yet).

Workarounds

Severity

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
