0ae01ce5e5bc18dc665dc946a08afd35b767fdb0 Add a frame ancestor range for walking the frame tree
not a security fix
confidence 0.15
signal score 6.47
Source/WebCore/dom
Classified as not security-relevant.
Triage note: Adds FrameAncestorIterator/FrameAncestorRange (holding RefPtr during traversal) and mechanically rewrites many ancestor-frame loops (CSP, X-Frame-Options, canAccessAncestor, etc.); a SaferCPP-style iteration-safety migration with no specific identified bug.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
