Changing PR:L to PR:N materially alters the base score and implied exploit prerequisites. Please ensure this vector exactly matches the authoritative source (e.g., MSRC/NVD) and that any computed numeric CVSS score fields (if present elsewhere in this advisory format) remain consistent with this vector; otherwise consumers may display conflicting severity/scoring.

With the severity bumped to CRITICAL, it would help to keep the record internally consistent by ensuring the severity aligns with the CVSS base score implied by the updated vector (and any severity mapping rules used in this repo). If the repo has a convention of deriving severity from CVSS rather than setting it manually, consider updating/adding a comment or metadata field indicating the source of the severity decision to reduce future churn.
