A small crafted brotli stream containing many empty meta-blocks with new Huffman trees can trigger hundreds of megabytes of allocations per kilobyte of input, leading to denial of service. #### Severity Unknown #### References - [https://github.com/andybalholm/brotli/security/advisories/GHSA-c9gr-gmg4-2vqv](https://redirect.github.com/andybalholm/brotli/security/advisories/GHSA-c9gr-gmg4-2vqv) - [https://github.com/andybalholm/brotli/commit/33c2a9884269798192b5ecf171288f98939dbe42](https://redirect.github.com/andybalholm/brotli/commit/33c2a9884269798192b5ecf171288f98939dbe42) - [https://github.com/andybalholm/brotli/releases/tag/v1.2.7](https://redirect.github.com/andybalholm/brotli/releases/tag/v1.2.7) - [https://github.com/google/brotli/commit/0ed4268a4401abcb4472096340477cf4af7d1a2b](https://redirect.github.com/google/brotli/commit/0ed4268a4401abcb4472096340477cf4af7d1a2b) This data is provided by [OSV](https://osv.dev/vulnerability/GO-2026-6888) and the [Go Vulnerability Database](https://redirect.github.com/golang/vulndb) ([CC-BY 4.0](https://redirect.github.com/golang/vulndb#license)). </details> --- ### Release Notes <details> <summary>andybalholm/brotli (github.com/andybalholm/brotli)</summary> ### [`v1.2.7`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.6...v1.2.7) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.6...v1.2.7) ### [`v1.2.6`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.5...v1.2.6) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.5...v1.2.6) ### [`v1.2.5`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.4...v1.2.5) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.4...v1.2.5) ### [`v1.2.4`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.3...v1.2.4) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.3...v1.2.4) ### [`v1.2.3`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.2...v1.2.3) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.2...v1.2.3) ### [`v1.2.2`](https://redirect.github.com/andybalholm/brotli/compare/v1.2.1...v1.2.2) [Compare Source](https://redirect.github.com/andybalholm/brotli/compare/v1.2.1...v1.2.2) </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
