Addressable 安全漏洞

Addressable is a Ruby library developed by Bob Aman. Versions of Addressable from 2.3.0 to 2.9.0 contained a security vulnerability. This vulnerability stemmed from the URI template implementation; two types of regular expressions generated by the URI templates had catastrophic backtracking, whic...

CVE-2026-34939

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.searchtools compiles a caller-supplied string directly as a Python regular expression with no validation, sanitization, or timeout. A crafted regex causes catastrophic backtracking in the re engine, blocking the Python...

PraisonAI Has ReDoS via Unvalidated User-Controlled Regex in MCPToolIndex.search_tools()

Summary MCPToolIndex.searchtools compiles a caller-supplied string directly as a Python regular expression with no validation, sanitization, or timeout. A crafted regex causes catastrophic backtracking in the re engine, blocking the Python thread for hundreds of seconds and causing a complete...

minimatch: Minimatch: Denial of Service via catastrophic backtracking in glob expressions

A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and...

AZL-81026 CVE-2026-33671 affecting package nodejs-nodemon 2.0.3-5

Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable to Regular Expression Denial of Service ReDoS when processing crafted extglob patterns. Certain patterns using extglob quantifiers such as + and , especially when combined with overlapping...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS when including multiple regular expression parameters in a single segment, separated by something that is not a period .. Poor performance will block the event loop and can lead to a DoS. Note:...

CVE-2026-4867

Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period .. For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two...

CVE-2026-22178 OpenClaw < 2026.2.19 - ReDoS and Regex Injection via Unescaped Feishu Mention Metadata

OpenClaw versions prior to 2026.2.19 construct RegExp objects directly from unescaped Feishu mention metadata in the stripBotMention function, allowing regex injection and denial of service. Attackers can craft nested-quantifier patterns or metacharacters in mention metadata to trigger catastroph...

All-Zero Key Generation on Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...

Quantifying Catastrophic Forgetting in IoT Intrusion Detection Systems

Distribution shifts in attack patterns within RPL-based IoT networks pose a critical threat to the reliability and security of large-scale connected systems. Intrusion Detection Systems IDS trained on static datasets often fail to generalize to unseen threats and suffer from catastrophic forgetti...

minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions

Summary Nested extglobs produce regexps with nested unbounded quantifiers e.g. ?:?:a|b, which exhibit catastrophic backtracking in V8. With a 12-byte pattern a|b and an 18-byte non-matching input, minimatch stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes...
