This advisory is unreviewed and has no package mapping, so it does not surface to users of the affected package.
The repository dgtlmoon/changedetection.io publishes the PyPI package
changedetection.io.The advisory names the SafeXPath3Parser blocklist and the json-doc() file access primitive. The fix commit (dadc8045, "XPath json-doc() Arbitrary File Read Bypass") adds json-doc, json-doc-available, collection, uri-collection, transform and load-xquery-module to the blocklist in changedetectionio/html_tools.py, with a regression test reading json-doc('file:///...'). This matches the advisory text.
I verified the boundary against the published PyPI wheels:
This is a distinct bypass from CVE-2026-29039 (unparsed-text(), fixed in 0.54.4, GHSA-6fmw-82m7-jq6p); this one covers json-doc() and was fixed in 0.54.7. It matches the "before 0.54.7" wording in the description and the release tag in the references (https://github.com/dgtlmoon/changedetection.io/releases/tag/0.54.7).
Proposed range: introduced 0, fixed 0.54.7.
The CVSS v4 vector was rewritten to omit the trailing Not Defined (X) metrics, which the form's validator rejects. Semantically identical per the CVSS v4.0 specification, no change to the severity assessment. CVSS v3 left untouched.
The advisory also had no title. The proposed one follows the database's naming convention and reflects the existing CWE-184 classification.
