Mozilla · Firefox · CVE-2023-37209
**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.
