CVE-2026-14895 String::Util versions before 1.36 for Perl are susceptible to a regular expression denial of service

String::Util versions before 1.36 for Perl are susceptible to a regular expression denial of service. The trim and rtrim functions stripped trailing whitespace with s/\s$//u. Because \s matches greedily and the $ anchor fails whenever a non-whitespace character follows the whitespace, the regex...

CVE-2026-14895

Summary: CVE-2026-14895 affects String::Util for Perl, versions before 1.36. The vulnerability arises in trim() and rtrim(), which strip trailing whitespace using a greedy regex (\s*$) that can cause quadratic backtracking on long whitespace runs, leading to CPU exhaustion. Root cause: regex back...
