| CVE-2023-47038 | Hig | 0.46 | 7.0 | 0.01 | Dec 18, 2023 | A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer. | ||
| CVE-1999-1386 | Med | 0.36 | 5.5 | 0.00 | Dec 31, 1999 | Perl 5.004_04 and earlier follows symbolic links when running with the -e option, which allows local users to overwrite arbitrary files via a symlink attack on the /tmp/perl-eaXXXXX file. | ||
| CVE-2025-40909 | Med | 0.31 | 5.9 | 0.00 | May 30, 2025 | Perl threads have a working directory race condition where file operations may target unintended paths.

| CVE-2024-56406 | Hig | 0.00 | 8.4 | 0.01 | Apr 13, 2025 | A heap buffer overflow vulnerability was discovered in Perl. Release branches 5.34, 5.36, 5.38 and 5.40 are affected, including development versions from 5.33.1 through 5.41.10. When there are non-ASCII bytes in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can… | ||
| CVE-2023-31486 | Hig | 0.00 | 8.1 | 0.02 | Apr 29, 2023 | HTTP::Tiny before 0.083, a Perl core module since 5.13.9 and available standalone on CPAN, has an insecure default TLS configuration where users must opt in to verify certificates. | ||
