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-39vw-qp34-rmwf in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- serde_yaml (crates.io): affected from 0.6.0-rc1; fixed in 0.8.4\n- serde_yaml (crates.io): affected from 0.6.0-rc1; fixed in 0.8.4\n- serde_yaml (crates.io): affected from 0.6.0-rc1; fixed in 0.8.4\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-39vw-qp34-rmwf/ (Markdown: https://insights.sbomify.com/GHSA-39vw-qp34-rmwf/index.md)","id":"GHSA-39vw-qp34-rmwf","markdown":"https://insights.sbomify.com/GHSA-39vw-qp34-rmwf/index.md","name":"GHSA-39vw-qp34-rmwf","record":{"aliases":["RUSTSEC-2018-0005"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust YAML library","requires_auth":"none","summary":"An attacker can cause a denial of service by providing a YAML file with self-referencing aliases, triggering uncontrolled recursion and aborting the application.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Affected versions of this crate did not properly check for recursion\nwhile deserializing aliases.\n\nThis allows an attacker to make a YAML file with an alias referring\nto itself causing an abort.\n\nThe flaw was corrected by checking the recursion depth.","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":"Uncontrolled recursion leads to abort in deserialization","id":"GHSA-39vw-qp34-rmwf","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.8.4"],"introduced":["0.6.0-rc1"],"last_affected":[],"package":"serde_yaml","purl":null,"source":"GHSA-39vw-qp34-rmwf"},{"ecosystem":"crates.io","fixed":["0.8.4"],"introduced":["0.6.0-rc1"],"last_affected":[],"package":"serde_yaml","purl":"pkg:cargo/serde_yaml","source":"GHSA-39vw-qp34-rmwf"},{"ecosystem":"crates.io","fixed":["0.8.4"],"introduced":["0.6.0-rc1"],"last_affected":[],"package":"serde_yaml","purl":"pkg:cargo/serde_yaml","source":"RUSTSEC-2018-0005"}],"products":null,"published":"2018-09-17","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 cause a denial of service by providing a YAML file with self-referencing aliases, triggering uncontrolled recursion and aborting the application.","url":"https://insights.sbomify.com/GHSA-39vw-qp34-rmwf/"}
