CVE-2026-13149

brace-expansion through 5.0.6 is vulnerable to denial of service. The expand function exhibits exponential-time complexity in the number of consecutive non-expanding '' brace groups. An attacker who passes a crafted string to expand, directly or transitively, can cause significant CPU consumption...

PT-2026-53832

Name of the Vulnerable Software and Affected Versions brace-expansion versions prior to 5.0.7 Description A denial of service issue exists where the expand function exhibits exponential-time complexity when processing consecutive non-expanding '' brace groups. An attacker can provide a crafted...

GHSA-CGXM-VR2F-6FJ8 parse-server: Denial of service via exponential-time processing of deeply nested query operators

Impact Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query 1 KB containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server...

Svelte 安全漏洞

Svelte is an open-source approach to building web applications. Versions of Svelte from 5.51.5 to 5.55.7 contained a security vulnerability. This vulnerability stemmed from the exponential increase in time taken for internal regular expression tests, which could lead to denial-of-service attacks...

Svelte: ReDoS in `<svelte:element>` Tag Validation

An internal regex in the Svelte runtime can take exponential time to test in . You are only vulnerable to this if you allow tags of unconstrained length. If your application only allows a predetermined list of tags or trims their length before passing them to svelte:element, you are safe...

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...

Cryptography from Lossy Reductions: Towards OWFs from ETH, and Beyond

One-way functions OWFs form the foundation of modern cryptography, yet their unconditional existence remains a major open question. In this work, we study this question by exploring its relation to lossy reductions, i.e., reductions$R$ for which it holds that $IX;RX \ll n$ for all distributions$X...
