Astra Linux – Vulnerability in node-ajv

The ajv Another JSON Schema Validator before version 8.18.0 is vulnerable to Regular Expression Denial of Service ReDoS when the $data option is enabled. The pattern keyword accepts runtime data via JSON Pointer syntax $data reference, which is passed directly to the JavaScript RegExp constructor...

Astra Linux – Vulnerability in node-minimatch

Minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.3, matchOne performed unbounded recursive backtracking when a glob pattern contained multiple non-adjacent GLOBSTAR...

Astra Linux – Vulnerability in ruby-addressable

Addressable is an alternative implementation to the URI implementation that is part of Ruby’s standard library. A vulnerability related to uncontrolled resource consumption exists in versions 2.3.0 through 2.7.0. In the URI template implementation provided by Addressable, a maliciously crafted...

Astra Linux – Vulnerability in Pypy

Python versions prior to 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1, and 3.7.0 are vulnerable to catastrophic backtracking in the difflib.IS-LineJUNK method. An attacker could exploit this flaw to cause a denial of service. source-iocs-preserved const=ISLINEJUNK...

Astra Linux – Vulnerability in ruby-websocket-extensions

The websocket-extensions Ruby module before version 0.1.5 allowed Denial of Service DoS attacks through Regex backtracking. The extension parser could take quadratic time when parsing a header containing an unclosed string parameter value whose content was a repeated two-byte sequence of a...

Astra Linux – Vulnerability in node-marked

Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression inline.reflinkSearch might cause catastrophic backtracking for certain strings, leading to a denial of service DoS attack. Any user who runs untrusted markdown using a vulnerable version of Marked, without...

Astra Linux – Vulnerability in Python 2.7, Pypy

In Python versions 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1, an HTTP server can perform Regular Expression Denial of Service ReDoS attacks against clients due to the use of urllib.request.AbstractBasicAuthHandler, which allows catastrophi...

CVE-2026-57577: Inefficient Regular Expression Complexity

DotVVM is an open source MVVM framework for web applications. Prior to 4.2.11, 4.3.15, and 5.0.0-preview09-final, a route containing multiple unconstrained parameters in one path segment can cause excessive regular-expression backtracking in DotvvmRoute.IsMatch when a remote requester supplies a...

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...
