Bookwyrm · Bookwyrm · CVE-2026-86113
**Name of the Vulnerable Software and Affected Versions**
BookWyrm versions prior to 0.9.2
**Description**
An authorization bypass exists in the `edit readthrough()` function. Authenticated users can exploit sequential ReadThrough IDs to modify reading records belonging to other users. This allows the unauthorized overwriting of `start dates`, `finish dates`, `progress`, and `progress mode`, which impacts reading statistics and exported data.
**Recommendations**
Update BookWyrm to version 0.9.2 or later.
As a temporary workaround, restrict access to the `edit readthrough()` function to minimize the risk of exploitation.
