Status: DeferredMedium (6.9)—

A flaw has been found in invariant-systems-ai aiir up to 1.7.0. The affected element is an unknown function of the component Policy Gate Handler. Executing a manipulation can lead to improper verification of cryptographic signature. The attack can be executed remotely. It is advisable to upgrade the affected component. The GitHub repository of this project is not available anymore. This vulnerability only affects products that are no longer supported by the maintainer.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques
