python: Python: Denial of Service via super-linear regular expression work in csv.Sniffer.sniff()

A flaw was found in the csv.Sniffer.sniff function within Python. An attacker can exploit this by providing specially crafted CSV samples, which can trigger super-linear regular-expression processing during dialect sniffing. This excessive processing consumes significant CPU resources, potentiall...

CVE-2026-67991: Inefficient Regular Expression Complexity

crmne/rubyllm at commit fa6f279847d6d7027814539d9c0dfc3bbdfd2a83 contains a polynomial-time regular expression denial-of-service condition in RubyLLM::Utils.underscore on Ruby 3.1.x. A very long crafted class, agent, or tool name can cause excessive CPU consumption and a denial of service...

CVE-2026-19487: Always-Incorrect Control Flow Implementation

Perl versions from 5.9.4 before 5.41.9 produce incorrect regular expression match results when a stale failure flag ends the Aho-Corasick prescan early in Sfindbyclass. The prescan walks the subject for positions where the full pattern could match, and the engine tries it from the leftmost one...

CVE-2026-73425

Astro is a web framework for content-driven websites. Prior to 8.1.2, the Astro Netlify adapter converts each image.remotePatterns entry into a regular expression written to .netlify/v1/config.json under images.remoteimages for Netlify's Image CDN allowlist. In...

CVE-2026-73088

Browserslist is a configuration tool for sharing target browsers and Node.js versions between front-end tools. Prior to 4.28.7, normalizeStats in node.js, reached unconditionally through getStat and loadStat on every browserslist call, processes untrusted browserslist-stats.json, opts.stats, and...

CVE-2026-18503

Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff...

CVE-2026-18503 Super-linear CPU usage for unbounded input to csv.Sniffer.sniff()

CVE-2026-19278

CVE-2026-19278 concerns StackRox/RHACS Central. The flaw lies in the Auth Machine-to-Machine (M2M) token exchange where, during M2M role mapping, unanchored regular expressions are used to match claim values. This allows an attacker with a valid OpenID Connect (OIDC) token whose claim value is a ...

CVE-2026-19278

A flaw was found in StackRox/RHACS Central's Auth Machine-to-Machine M2M token exchange. When an administrator configures M2M role mappings, the system uses unanchored regular expressions for matching claim values. This allows an attacker with a valid OpenID Connect OIDC token, whose claim value ...

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...

Open WebUI: Any authenticated user can stall a worker via a knowledge-search pattern that backtracks catastrophically

SummaryThe built-in knowledge search tools let a chat participant choose the pattern used to grep knowledge files. Patterns containing regex metacharacters were compiled with Python's backtracking re engine and run against every line of every reachable file, with no time limit anywhere on that...
