CVE-2026-115352
Mistune versions before 3.3.0 are vulnerable to an algorithmic complexity issue in the inline link parser . An unauthenticated attacker can submit small markdown payloads containing long sequences of unmatched '[' characters to trigger O(N^2) parse_link_text and parse_link_label probing. This all...
CVE-2026-104477
A flaw was found in showdown. The link and image parsers fail to properly sanitize or escape double quotation marks in destination URLs when rendering HTML attributes. A remote attacker could exploit this flaw by supplying crafted Markdown input containing malicious event handlers, leading to...
