GHSA-J4R3-HG7J-8CHG node-re2: Out-of-bounds heap read in `replace`/`split` via a `Buffer` ending in a truncated multi-byte UTF-8 character → adjacent heap memory disclosed to JavaScript

Summary re2 infers a character's byte length from its UTF-8 lead byte alone, with no bound on the bytes actually remaining in the input. Buffer arguments reach the native layer verbatim — only strings are re-encoded into well-formed UTF-8 — so a Buffer whose last byte is a multi-byte lead promise...

GHSA-8HCV-X26H-MCGP node-re2: String.prototype.replace(re2, template) aborts the Node process (uncatchable ToLocalChecked on empty MaybeLocal) when the result exceeds V8's max string length

Description WrappedRE2::Replace builds the replacement result and hands it to V8 with .ToLocalChecked without checking for the empty MaybeLocal that V8 returns when the string/buffer exceeds its maximum length: lib/replace.cc v1.24.1: cpp // L553 — Buffer return path...

GHSA-MH25-X5HQ-WRQP league/commonmark: Denial of service via colliding heading slugs

Impact UniqueSlugNormalizer::normalize makes each slug document-unique by searching for an unused numeric suffix, but restarts that search from 1 on every collision. The k-th heading that collapses to the same base slug performs k−1 array lookups, so K colliding slugs cost Σk−1 = OK². An attacker...

GHSA-JFM3-95JQ-Q3RF league/commonmark: Denial of service via duplicate footnote definitions

Impact The Footnote extension records one backref per footnote reference and then appends the entire backref list for every footnote definition block in the document, without ever de-duplicating or removing repeated definitions of the same label GatherFootnotesListener, populated by...

GHSA-G2GP-3WWQ-F4PH league/commonmark: Denial of service via adjacent inline attribute blocks

GHSA-C4C3-PG64-4M4V Mermaid configuration APIs allow prototype pollution

Summary Mermaid's configuration setters mermaid.initialize, mermaidAPI.setConfig, and mermaidAPI.updateSiteConfig merge the caller-supplied configuration object into Mermaid's internal config using the assignWithDepth deep-merge helper that is vulnerable to prototype pollution. Because these APIs...

GHSA-6X64-9X62-F2GX Mermaid allows CSS injection applying to sibling elements of the diagram

Summary Mermaid does not fully restrict CSS to the rendered SVG subtree. Although selectors are prefixed with mermaid-X, sibling and + combinators can still escape the Mermaid container and inject styles to DOM elements adjacent to the diagram . Most users of mermaid would not be affected by this...

GHSA-3RRR-JR9J-H3Q3 Mermaid Architecture diagrams are vulnerable to prototype pollution

Rendering an untrusted architecture-beta diagram lets the diagram author write an arbitrary property with the value horizontal or vertical onto Object.prototype.
