{"id":"CVE-2026-33241","summary":"Salvo Affected by Denial of Service via Unbounded Memory Allocation in Form Data Parsing","details":"Salvo is a Rust web framework. Prior to version 0.89.3, Salvo's form data parsing implementations (`form_data()` method and `Extractible` macro) do not enforce payload size limits before reading request bodies into memory. This allows attackers to cause Out-of-Memory (OOM) conditions by sending extremely large payloads, leading to service crashes and denial of service. Version 0.89.3 contains a patch.","aliases":["GHSA-pp9r-xg4c-8j4x"],"modified":"2026-04-10T05:42:40.171239Z","published":"2026-03-23T23:41:50.533Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33241.json","cwe_ids":["CWE-770"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33241.json"},{"type":"WEB","url":"https://github.com/salvo-rs/salvo/releases/tag/v0.89.3"},{"type":"ADVISORY","url":"https://github.com/salvo-rs/salvo/security/advisories/GHSA-pp9r-xg4c-8j4x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33241"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/salvo-rs/salvo","events":[{"introduced":"0"},{"fixed":"f8fb007c4c765dd0a4961f81846e6f27629dcd28"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.89.3"}]}}],"versions":["v0.18.3","v0.18.4","v0.19.0","v0.19.1","v0.20.0","v0.21.0","v0.21.1","v0.21.2","v0.21.3","v0.21.4","v0.21.5","v0.21.7","v0.22.0","v0.22.1","v0.22.2","v0.23.0","v0.23.1","v0.23.2","v0.23.3","v0.24.0","v0.24.1","v0.24.2","v0.24.4","v0.25.0","v0.25.1","v0.26.0","v0.26.1","v0.27.0","v0.28.1","v0.28.2","v0.29.0","v0.29.1","v0.30.0","v0.31.0","v0.31.1","v0.32.0","v0.33.1","v0.33.2","v0.34.2","v0.34.3","v0.35.1","v0.35.2","v0.36.0","v0.37.0","v0.37.1","v0.37.2","v0.41.1","v0.42.0","v0.42.1","v0.43.0","v0.44.0","v0.44.1","v0.45.0","v0.46.0","v0.47.0","v0.48.0","v0.48.1","v0.48.2","v0.49.0","v0.49.1","v0.50.1","v0.50.2","v0.50.3","v0.50.4","v0.50.5","v0.51.0","v0.52.0","v0.52.1","v0.53.0","v0.54.0","v0.54.1","v0.54.3","v0.55.0","v0.55.1","v0.55.2","v0.55.3","v0.55.4","v0.55.5","v0.56.0","v0.57.0","v0.58.0","v0.58.1","v0.58.2","v0.58.3","v0.58.4","v0.58.5","v0.59.0","v0.59.1","v0.60.0","v0.61.0","v0.63.0","v0.63.1","v0.64.0","v0.64.1","v0.64.2","v0.65.0","v0.65.1","v0.65.2","v0.66.1","v0.66.2","v0.67.0","v0.67.1","v0.67.2","v0.68.0","v0.68.1","v0.68.2","v0.68.3","v0.68.4","v0.68.5","v0.69.0","v0.70.0","v0.71.0","v0.71.1","v0.72.0","v0.72.1","v0.72.2","v0.72.3","v0.72.4","v0.73.0","v0.74.0","v0.74.1","v0.74.2","v0.74.3","v0.75.0","v0.76.0","v0.76.1","v0.76.2","v0.77.0","v0.77.1","v0.78.0","v0.79.0","v0.80.0","v0.81.0","v0.82.0","v0.83.0","v0.84.0","v0.84.1","v0.84.2","v0.85.0","v0.86.0","v0.87.0","v0.87.1","v0.88.0","v0.88.1","v0.89.0","v0.89.1","v0.89.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33241.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
