joi: Quadratic regular-expression backtracking in `Joi.string().isoDate()`

Impact Any application that validates a user-supplied string with Joi.string.isoDate can be stalled by a single request. One of the regular expressions the rule runs over the input was unanchored, so a valid ISO date followed by a long run of fractional-second digits made the regex engine restart...

CVE-2026-102270

A flaw was found in PyJWT. An attacker can cause a Denial of Service DoS by providing crafted certificate-like input containing repeated start markers without matching end markers. This malformed input triggers excessive regular expression backtracking during validation in the ispemformat functio...

CVE-2026-102270

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT ispemformat is affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like input contains repeated BEGIN markers without a matching END marker. As a result, ispemforma...

CVE-2026-57577: Inefficient Regular Expression Complexity

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 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...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could create specific hostnames that, when processed by the matchpattern function, could lead to inefficient regular expression backtracking. This could cause timeouts and resource...
