{"id":"CVE-2026-54615","published":"2026-10-23T04:18:16.833","lastModified":"2026-10-23T19:36:32.410","description":"Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.1, LogEntryExtraFormatter builds the HTML shown in the \"Extra\" column of the activity-log table (/log) and in element history tables. Every branch of LogEntryExtraFormatter::getInternalFormat() runs user-controlled strings through htmlspecialchars() before placing them into the HTML it returns — except the CollectionElementDeleted branch, which interpolates getOldName() (and getCollectionName()) into a sprintf() template with no escaping. The returned string is emitted by LogEntryExtraColumn::render() and inserted as raw HTML into the DataTables cell (the bundle does not escape column output; sibling columns call htmlspecialchars() themselves). CollectionElementDeleted.getOldName() is the name of a deleted collection sub-element — a part Parameter, Attachment, PartLot, Orderdetail, etc. — all freely set by any user with edit rights on the owning element. A low-privileged content editor can therefore store an HTML/script payload as the name of such a sub-element, delete it (which writes the log entry), and have that markup parsed as live DOM in the browser of a higher-privileged victim (an administrator/auditor with system.show_logs, or any user viewing that element's history). This is a stored cross-site-scripting / HTML-injection defect caused by a single missed sanitizer in one sibling branch. CSP policies block inline javascript execution under normal conditions. This issue has been patched in version 2.12.1.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Part-DB/Part-DB-server/releases/tag/v2.12.1","tags":[]},{"url":"https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-gp89-jfq9-x8r9","tags":[]}],"exploitRefs":[{"url":"https://github.com/Part-DB/Part-DB-server/releases/tag/v2.12.1","tags":[]},{"url":"https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-gp89-jfq9-x8r9","tags":[]}],"hasPoc":true,"ai":null}
