GHSA-8X48-8G7J-RQXP Duplicate Advisory: Quadratic-time DoS in PorterStemmer via long runs of 'y'

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-ww6m-cw3f-q94g. This link is maintained to preserve external references. Original Description nltk PorterStemmer in versions = 3.10.2 fixed in 3.10.3 contains an inefficient-algorithmic-complexity denial of...

CVE-2026-59276 Timing Attack via Non-Constant-Time Comparison of Sensitive Values

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

CVE-2026-59276

Spring Security is affected by a timing attack vulnerability in several components that compare security-sensitive values using standard String.equals() instead of a constant-time comparison. Because String.equals() returns as soon as a differing character is found, the response time for rejectin...

CVE-2026-81722 nltk PorterStemmer before 3.10.3 Quadratic-time DoS

nltk PorterStemmer in versions = 3.10.2 fixed in 3.10.3 contains an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem. The isconsonant helper walks backward over the entire run of trailing 'y' characters on every call, and measure invokes it for each stem position, causin...

CVE-2026-81722

nltk PorterStemmer in versions ≤ 3.10.2 is vulnerable to an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem(). The root cause is that the _is_consonant() helper walks backward over the entire run of trailing 'y' characters on every call, and _measure() invokes it for ea...

CVE-2026-81722 nltk PorterStemmer before 3.10.3 Quadratic-time DoS

Inefficient Algorithmic Complexity

Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the PorterStemmer.stem path in nltk/stem/porter.py. An attacker can pin a CPU core by supplying a single...

CVE-2026-59641

A flaw was found in Bouncy Castle for Java. The S/MIME Secure/Multipurpose Internet Mail Extensions validator improperly trusts the signing time asserted by the signer during path validation. This could allow an attacker to bypass certificate path validation, potentially leading to the acceptance...
