Detailsinfo

A vulnerability was found in aeon-toolkit aeon up to 1.4.x. It has been classified as critical. Affected is an unknown code. The manipulation with an unknown input leads to a behavioral workflow vulnerability. CWE is classifying the issue as CWE-841. The product supports a session in which more than one behavior must be performed by an actor, but it does not properly ensure that the actor performs the behaviors in the required sequence or timeframe. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

aeon is a scikit-learn compatible Python library for learning from time series. Prior to version 1.5.0, a GitHub Actions workflow used pull_request_target for pre-commit checks on pull requests from forks. In this configuration, fork-controlled code could be checked out and executed in a privileged context. The vulnerable workflow also generated/used elevated credentials and could automatically commit or push fixes back to pull request branches. This created a potential token exposure and repository write path if an attacker submitted a malicious fork pull request designed to execute during the privileged workflow run. This issue has been patched in version 1.5.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-65820 since 07/23/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

Upgrading to version 1.5.0 eliminates this vulnerability.
