CVE-2026-84305

A flaw was found in sqlparse, a non-validating SQL parser module for Python. A remote attacker could exploit this by providing specially crafted parenthesized tuple lists. When these lists are reindentated, the software performs numerous offset calculations, leading to quadratic CPU consumption...

probe-image-size: Quadratic-time Denial of Service in the SVG Parser

Overview probe-image-size scans the SVG header with a searching regular expression, //. On input that contains many , the engine restarts the ^ scan at every position and runs to end of input each time, giving quadratic time complexity. Both the synchronous and the streaming parser are affected...

CVE-2026-104861 probe-image-size: Quadratic-time Denial of Service in the SVG Parser

probe-image-size gets image dimensions without downloading the entire file. Prior to 7.4.0, lib/parsesync/svg.js and lib/parsestream/svg.js use the searching regular expression //, which repeatedly scans to the end of input when attacker-controlled data contains many less-than characters without ...

CVE-2026-104844

A flaw was found in postcss-selector-parser. A remote attacker could exploit this vulnerability by submitting a specially crafted CSS selector containing numerous class or ID identifiers to an application that parses untrusted input. Due to inefficient processing and repeated scanning during...

CVE-2026-104844

PostCSS Selector Parser is a CSS selector parser that integrates with PostCSS but does not require it. Prior to 7.1.6, src/parser.js splitWord can receive a flat selector as one word token carrying many class or ID indexes because period and hash characters are not tokenizer word delimiters. The...
