{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/72444?format=json","vulnerability_id":"VCID-vfnf-qxyy-1yhx","summary":"@fastify/accepts-serializer cached serializer-selection results keyed by the request Accept header without a size limit or eviction policy. A remote unauthenticated client could send many distinct but matching Accept header variants to make the cache grow unbounded, eventually exhausting the Node.js heap and crashing the process. Versions <= 6.0.3 are affected. Update to 6.0.4 or later, which bounds the cache via an LRU with a default size of 100 entries, configurable through the new cacheSize plugin option.","aliases":[{"alias":"CVE-2026-7768"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-7768","reference_id":"","reference_type":"","scores":[{"value":"0.00053","scoring_system":"epss","scoring_elements":"0.168","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-7768"},{"reference_url":"https://github.com/fastify/fastify-accepts-serializer/security/advisories/GHSA-qxhc-wx3p-2wmg","reference_id":"GHSA-qxhc-wx3p-2wmg","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-04T19:50:08Z/"}],"url":"https://github.com/fastify/fastify-accepts-serializer/security/advisories/GHSA-qxhc-wx3p-2wmg"},{"reference_url":"https://cna.openjsf.org/security-advisories.html","reference_id":"security-advisories.html","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-04T19:50:08Z/"}],"url":"https://cna.openjsf.org/security-advisories.html"}],"weaknesses":[{"cwe_id":770,"name":"Allocation of Resources Without Limits or Throttling","description":"The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor."}],"exploits":[],"severity_range_score":"7.5 - 7.5","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-vfnf-qxyy-1yhx"}
