GitLab CE/EE 19.5.0 Regular Expression Integer Overflow

GitLab CE/EE versions before 18.11.13, 19.0.10, 19.1.9, 19.2.9, 19.3.6, 19.4.3, and 19.5.1 contain a regular expression compiler integer overflow that may allow unauthenticated arbitrary code execution. This proof of concept generates crafted Org-mode content and triggers the affected render path...

Medium: perl

Issue Overview: Perl versions through 5.45.1 have out-of-bounds heap reads and writes during regular expression matching via an undersized superlinear cache in Sregmatch. The regex engine's superlinear cache holds one bit per subject position for each participating WHILEM node, so the bit count i...

ruby: integer overflow issue in regular expression compiler

A flaw was found in Ruby. When compiling a specially crafted regular expression containing an excessive number of repeats with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, an integer overflow of internal IDs can occur. This integer overflow...

ruby: integer overflow issue in regular expression compiler

A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, an integer overflow in the size of the compiled pattern can occur. This integer overflow causes memory...

ruby: double free issue in regular expression parser

A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, a double free can occur when parsing a pattern that fails after an alternation. This double free causes memory...

CVE-2026-115887

The graphql-scalars library contains a Regular Expression Denial of Service (ReDoS) vulnerability in the GraphQLPhoneNumber scalar (located in src/scalars/PhoneNumber.ts). Affected versions range from 1.24.1 until 2.0.1 . The root cause is the use of ambiguous nested digit quantifiers, which caus...

CVE-2026-113877

The HTTP::Headers::ActionPack module for Perl (versions before 0.10 ) is vulnerable to CPU exhaustion via the Accept-Language header. The root cause is that the _language_match function interpolates ranges into a regular expression pattern without proper escaping, allowing attackers to inject com...
