+  "details": "## Summary\n\nThe `/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.\n\n## Impact\n\nUnauthenticated users could bypass configured retention expectations for secrets they create by sending `POST /api/create?expire=-1`.\n\nThis 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.\n\n## Affected versions\n\nVersions up to and including v1.21.4 are affected.\n\n## Patched versions\n\nFixed in v1.21.5.\n\n## Workarounds\n\nDisable expiry overrides via `disableExpiryOverride: true` until upgrading.\n\n## Credit\n\nReported by Chai Cheng Xun via email.",
