ots has a negative expire override that can bypass its secret retention policy
GHSA-h5fq-653g-gxrm
- Affected
- Go github.com/Luzifer/ots <= 1.21.4
- Fixed in
- 1.21.5· Vendor fix available
- Issue
- The /api/create endpoint accepted negative expire query values. For the memory storage backend, negative values were passed to secret creation as a negative duration and treated as no expiry, allowing callers to create secrets that persisted longer than intended. Impact Unauthenticated users could bypass configured retention expectations for secrets they create by sending POST /api/create?expire=-1. This does not allow reading or modifying secrets created by other users. Secrets remain one-time-read and, in the normal web flow, client-side encrypted. Affected versions Versions up to and including v1.21.4 are affected. Patched versions Fixed in v1.21.5. Workarounds Disable expiry overrides via disableExpiryOverride: true until upgrading.

Recommended action: Upgrade to 1.21.5 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
