UBUNTU-CVE-2026-71488

league/commonmark is a PHP library for parsing and rendering CommonMark Markdown. From 0.6.0 until 2.9.0, specially crafted Markdown lines can cause the parser to have quadratic time complexity when converting, because several parsing paths repeatedly rescan growing portions of a line to translat...

CVE-2026-61632 PyMdown Extensions: Path traversal in the b64 extension lets <img src> read files outside base_path

PyMdown Extensions is a set of extensions for the Python-Markdown markdown project. In versions up to and including 10.21.3, the b64 extension is vulnerable to a path traversal that discloses arbitrary files: it inlines images referenced by by joining the src onto the configured basepath with...

CVE-2026-61632

CVE-2026-61632 affects PyMdown Extensions (b64 extension) up to version 10.21.3. The b64 code path in pymdownx/b64.py joins the attacker-controlled image src onto a configured base_path (or uses an absolute path) and opens the result without ensuring the resolved path stays inside base_path, allo...

league/commonmark: Quadratic-time denial of service when parsing crafted Markdown

Impact Affected versions of league/commonmark can have quadratic time complexity when parsing specially crafted Markdown lines. In practical terms, doubling the length of an affected line can make the parser perform roughly four times as much work. The parser identifies locations using character...
