 https://cve.radiocsirt.org/vuln/ghsa-2ww3-fxvq-293j GHSA-2ww3-fxvq-293j — NLTK Vulnerable to REDoS 2026-10-06T12:47:17.046062+00:00

Affected: PyPI: nltk

The nltk package is vulnerable to ReDoS (regular expression denial of service). An attacker that is able to provide as an input to the [`_read_comparison_block()`(https://github.com/nltk/nltk/blob/23f4b1c4b4006b0cb3ec278e801029557cec4e82/nltk/corpus/reader/comparative_sents.py#L259) function in the file `nltk/corpus/reader/comparative_sents.py` may cause an application to consume an excessive amount of CPU.
