An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-fx4f-mhw4-qm7j in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- vibeio-http (crates.io): affected all versions; fixed in 0.3.2\n- vibeio-http (crates.io): affected all versions; fixed in 0.3.2\n- vibeio-http (crates.io): affected from 0.0.0-0; fixed in 0.3.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-fx4f-mhw4-qm7j/ (Markdown: https://insights.sbomify.com/GHSA-fx4f-mhw4-qm7j/index.md)","id":"GHSA-fx4f-mhw4-qm7j","markdown":"https://insights.sbomify.com/GHSA-fx4f-mhw4-qm7j/index.md","name":"GHSA-fx4f-mhw4-qm7j","record":{"aliases":["RUSTSEC-2026-0181"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust HTTP library","requires_auth":"none","summary":"An attacker can crash the server by sending a malicious HTTP request with an excessively large chunk length, causing an integer overflow panic.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"When using the affected versions of the `vibeio-http` crate, an attacker could craft a malicious HTTP/1.x request with a large chunk length (between `usize::MAX - 1` and `usize::MAX` inclusive) and send it, causing the server to crash (integer overflow panic in debug builds, split_to out of bounds panic in release builds).\n\nThis was fixed in `vibeio-http` 0.3.2 by erroring on the chunk length if it exceeds `usize::MAX - 2` (using `checked_add()` instead of `+` operator), preventing integer overflow.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"vibeio-http has a DoS vulnerability in HTTP/1.x chunked encoding parser triggered by maliciously crafted chunk lengths","id":"GHSA-fx4f-mhw4-qm7j","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.3.2"],"introduced":["0"],"last_affected":[],"package":"vibeio-http","purl":null,"source":"GHSA-fx4f-mhw4-qm7j"},{"ecosystem":"crates.io","fixed":["0.3.2"],"introduced":["0"],"last_affected":[],"package":"vibeio-http","purl":"pkg:cargo/vibeio-http","source":"GHSA-fx4f-mhw4-qm7j"},{"ecosystem":"crates.io","fixed":["0.3.2"],"introduced":["0.0.0-0"],"last_affected":[],"package":"vibeio-http","purl":"pkg:cargo/vibeio-http","source":"RUSTSEC-2026-0181"}],"products":null,"published":"2026-06-06","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can crash the server by sending a malicious HTTP request with an excessively large chunk length, causing an integer overflow panic.","url":"https://insights.sbomify.com/GHSA-fx4f-mhw4-qm7j/"}
