CVE-2026-14895

The String::Util module for Perl (versions before 1.36 ) is vulnerable to a Regular Expression Denial of Service (ReDoS) . The trim and rtrim functions use the regex s/\s*$//u to strip trailing whitespace. Because \s* matches greedily, the engine performs quadratic backtracking when it encounters...

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...
