Name of the Vulnerable Software and Affected Versions lockss-daemon versions prior to 1.77.3

Description The issue is related to post-Unicode normalization, which may allow bypass of intended access restrictions. This can occur when certain Unicode characters, such as U+1FEF, are converted to other characters, like a backtick.

Recommendations For versions prior to 1.77.3, update to version 1.77.3 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive areas where Unicode normalization could be exploited until a patch is applied.
