PYSEC-2026-3871 NLTK: Quadratic CPU Exhaustion in `XMLCorpusView._read_xml_fragment()`

Summary XMLCorpusView.readxmlfragment reads a corpus file in 1 KiB blocks, appending each block to a growing fragment string, then calls VALIDXMLRE.matchfragment on the full accumulated buffer every iteration. Because each iteration rescans the entire accumulated fragment, the total amount of wor...

NLTK TweetTokenizer vulnerable to denial of service through catastrophic regex backtracking

The URLS regular expression in nltk/tokenize/casual.py, compiled into TweetTokenizer.WORDRE and applied by TweetTokenizer.tokenize, contains a naked-domain branch whose domain-label prefix a-z0-9+?:.\-a-z0-9+ is unbounded. Input consisting of many alternating label separators can be partitioned i...

GHSA-X4FP-J954-R2F4 xmldom: End-tag Whitespace-Trim Regex ReDoS — quadratic backtracking in the 0.8.x end-tag parser

Summary On the @xmldom/xmldom 0.8.x line, parsing an XML end tag whose name is followed by a long run of whitespace and then a non-whitespace character triggers quadratic-time regular-expression backtracking ReDoS, so a single small crafted end tag stalls the Node.js event loop. It is reachable...

Colord: Slow rejection of oversized malformed color strings

Impact colord's CSS color string matchers described a number as +-?\d.?\d+. In that form \d and \d+ can match the same digits, so a run of n digits can be divided between them in On² ways, and rejecting an input retries every division. Parsing is synchronous and uninterruptible, so a long...
