Short explanation
In Part-DB‑server versions prior to 2.12.1, the CollectionElementDeleted branch of LogEntryExtraFormatter fails to escape user input, inserting raw HTML into the “Extra” column. A low‑privileged content editor can store a malicious script as the name of a deleted sub‑element; the payload is rendered when a higher‑privileged administrator views the log.
A stored XSS can execute malicious code in an administrator’s browser and lead to credential theft.
What should be done?
- Upgrade Part-DB‑server to version 2.12.1 or later
- Follow the vendor’s security advisory
- Add additional HTML escaping for the affected fields
- Enforce a strict Content Security Policy
- Audit logs for malicious entries

Show the technical text from the sources
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.
