High

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Firefox versions prior to 115
Description A use-after-free condition existed in NotifyOnHistoryReload where a LoadingSessionHistoryEntry object was freed and a reference to that object remained. This resulted in a potentially exploitable condition when the reference to that object was later reused.
Recommendations For versions prior to 115, update to version 115 or later to resolve the issue. As a temporary workaround, consider disabling the NotifyOnHistoryReload function until a patch is available.
