CVE-2026-16270: Inefficient Regular Expression Complexity

Open Mercato does not validate regex rules. An attacker with privileges to create the regex rule can add an unsafe regex to a field. When someone provide the proper string it can result in a DoS attack. This issue was fixed in version 0.6.4...

Tornado: Quadratic DoS via Crafted Multipart Parameters

Summary The parseparam function in Tornado's httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data. This function uses an inefficient algorithm that repeatedly calls string.count within a nested loop while processing quoted semicolons e.g., param=";". As a...

CVE-2026-59869: Inefficient Algorithmic Complexity

js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 before 3.15.0 and from 4.0.0 before 4.3.0, js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of mappings uses merge keys where each mapping merges the previous one. This issue is fixed in...

CVE-2026-59887: Inefficient Algorithmic Complexity

linkify-it is a links recognition library with full Unicode support. Prior to 5.0.2, the mailto: schema validator used by .test and .match can be invoked at every mailto: occurrence and scan the remaining input through srcemailname in lib/re.mjs, causing On^2 CPU consumption on crafted user text...

CVE-2026-59928: Inefficient Algorithmic Complexity

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, a Markdown document containing many repeated or distinct reference-link definitions causes quadratic work in src/mistune/blockparser.py and the reflinks environment dictionary handling, allowing denial of service...

CVE-2026-59922: Inefficient Algorithmic Complexity

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, a run of closed tilde, equals-sign, or caret marker pairs around a character causes quadratic work in src/mistune/plugins/formatting.py when the strikethrough, mark, or insert plugin scans for matching markers from ea...

CVE-2026-55206: Inefficient Algorithmic Complexity

py7zr is a Python-based library and utility to support 7zip archive compression, decompression, encryption and decryption. Prior to 1.1.3, PackInfo.read in archiveinfo.py used an On^2 cumulative sum pattern for attacker-controlled numstreams values parsed from archive headers, allowing a crafted...

The vulnerability of the library for filtering file paths in Picomatch, which stems from the use of a regular expression c with inefficient computational complexity, allows attackers to trigger a service failure.

The vulnerability of the library for filtering file paths in Picomatch is related to the use of a regular expression with inefficient computational complexity. Exploiting this vulnerability could allow an attacker operating remotely to cause service interruptions...

CVE-2026-59868: Inefficient Algorithmic Complexity

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 before 5.2.0, when merge keys are enabled, js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of mappings uses merge keys where each mapping merges the previous one. This issue is fixed in...
