DotVVM is an open source MVVM framework for web applications. Prior to 4.2.11, 4.3.15, and 5.0.0-preview09-final, a route containing multiple unconstrained parameters in one path segment can cause excessive regular-expression backtracking in DotvvmRoute.IsMatch when a remote requester supplies a...

PYSEC-2026-3654 pymdown-extensions: exponential-backtracking ReDoS in caret, tilde, betterem, and magiclink inline processors

Summary Four inline processors in pymdown-extensions contain regular expressions with exponential backtracking. A single untrusted Markdown line under 50 bytes drives markdown.markdown into unbounded CPU on the rendering thread seconds at 45 bytes, growing exponentially with each added character...

CVE-2026-49477

A flaw was found in soupsieve, a CSS selector library. This vulnerability allows a remote attacker to cause a Denial of Service DoS by supplying specially crafted, untrusted CSS selector strings. The flaw occurs due to a regular expression vulnerable to catastrophic backtracking when processing a...

CVE-2026-49477 Soup Sieve: Regular Expression Denial of Service (ReDoS) in soupsieve Selector Parser

Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. Prior to 2.8.4, the CSS selector parser in soupsieve contains a regular expression vulnerable to catastrophic backtracking when processing an attribute selector with an unterminated quoted value in...

CVE-2026-45756 Symfony: JsonPath Evaluates Attacker-Controlled Regular Expressions in match()/search() Without Limits — ReDoS

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 7.3.0-BETA1 until 7.4.12 and 8.0.12, the JsonPath component compiles attacker-controlled match and search filter patterns directly into pregmatch without a length cap, i-regexp restriction, or...

Security Bulletin: Multiple Vulnerabilities in Minimatch bundled with IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage

Summary IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage include the minimatch library, which is susceptible to multiple Denial of Service DoS vulnerabilities due to algorithmic inefficiencies and catastrophic regular expression backtracking. A remote attacker could exploit these...

org.hl7.fhir.core: ReDoS via FHIRPath matches()/replaceMatches() in FHIR Validator HTTP Endpoint

All implementations of FHIRPathEngine accept arbitrary FHIRPath expressions and evaluate them without input validation. The utility intended to secure this evaluation did so incorrectly, and did not fully cover all places in which evaluation was being done. An attacker can send a resource...

ReDoS in giskard's transformation.py (GHSL-2024-324)

ReDoS in Giskard text perturbation detectorA Remote Code Execution ReDoS vulnerability was discovered in Giskard component by the GitHub Security Lab team. When processing datasets with specific text patterns with Giskard detectors, this vulnerability could trigger exponential regex evaluation...

multiparty vulnerable to ReDoS via filename parsing

Impact [email protected] and lower versions are vulnerable to denial of service via regular expression backtracking in the Content-Disposition filename parameter parser. A multipart upload with a long header value containing !filename="1 repeated can cause regex matching to take seconds, blocking...

Summary IBM Watson Discovery Cartridge affected by vulnerabilities in minimatch-3.1.2.tgz Vulnerability Details CVEID:CVE-2026-26996 DESCRIPTION: minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Versions 10.2.0 and below are vulnerable to...

Nokogiri CSS selector tokenizer has regular expression backtracking

Summary Nokogiri's CSS selector tokenizer contains regular expressions whose construction may result in exponential regex backtracking on adversarial selectors. Three ReDoS vectors are addressed in this release: 1. String-literal tokenization on certain unterminated quoted-string input. 2...

CVE-2026-33079

In versions 3.0.0a1 through 3.2.0 of Mistune, there is a ReDoS Regular Expression Denial of Service vulnerability in LINKTITLERE that allows an attacker who can supply Markdown for parsing to cause denial of service. The regular expression used for parsing link titles contains overlapping...

CVE-2026-33079

Mistune 3.0.0a1–3.2.0 contains a ReDoS in LINK_TITLE_RE used for parsing link titles, enabling exponential backtracking when processing Markdown strings with repeated ! sequences and no closing quote. The ambiguity arises from overlapping alternatives in the two branches (double-quoted and single...

CVE-2026-33079

In versions 3.0.0a1 through 3.2.0 of Mistune, there is a ReDoS Regular Expression Denial of Service vulnerability in LINKTITLERE that allows an attacker who can supply Markdown for parsing to cause denial of service. The regular expression used for parsing link titles contains overlapping...

GHSA-8MP2-V27R-99XP Mistune has a ReDoS in LINK_TITLE_RE that allows denial of service via crafted Markdown input

Summary A ReDoS Regular Expression Denial of Service vulnerability in LINKTITLERE allows an attacker who can supply Markdown for parsing to cause denial of service. A crafted 58-byte Markdown document blocks the parser for approximately 6 seconds measured on Apple M2, Python 3.14.3, with...
