The October recap covers several different failure modes. A software patch, a compromised package and an exposed credential require different checks. Start by listing which affected products you actually run.

## Check the deployed runtime

Use the [PHP update guide](/blog/php-critical-security-update-check) and [Python certificate guide](/blog/python-emudhra-certificate-update) for their respective notices.

For self-managed GitLab, compare your release with the October critical patch notice. Custom installations using a separate Ruby runtime also need Ruby updated; upgrading GitLab alone does not supply that fix. [1]

## Check package exposure before reinstalling

For LiteLLM, use the [artifact and recovery guide](/blog/litellm-compromised-release-response). The incident notice warns against starting Python or pip in an affected environment before cleanup. [2]

OVHcloud's advisory identifies replaced CLI release binaries downloaded during a specific October 19 window. Check its platform, time and artifact details before deciding whether your installation was exposed. [5]

## Revoke exposed credentials

Railway recommends replacing sensitive environment variables stored before October 21. Zeabur's follow-up likewise tells affected users to revoke or rotate stored keys and inspect related charges. Follow each provider's current incident instructions. [3][4]

For Palo Alto equipment, identify the product and installed version in the official advisory search. The recap caption does not name a CVE, so it is insufficient to select a particular patch. [6]

Keep banking passwords out of agent prompts. Use your bank's own supported login and authorization flow for any account access, and review transactions yourself.
