{"apiVersion":"1.0","identifier":"CVE-2026-73507","description":"Netty is an asynchronous, event-driven network application framework. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.xml.XmlFrameDecoder.decode() failed to preserve closing-tag parser state across invocations, so an unauthenticated remote attacker could trickle-feed repeated </ sequences that repeatedly rescanned the accumulated buffer and exhausted an EventLoop thread-s CPU, causing denial of service with a maxFrameLength of 1 MB. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.","publishedAt":"2026-08-13T15:20:17","lastModifiedAt":"2026-08-15T04:18:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73507","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00455,"riskScore":0.78,"affectedProduct":"Netty","affectedVersions":"cannotmatch","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73507","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73507","en":"https://www.redsauce.net/en/cves/CVE-2026-73507","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73507","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73507","de":"https://www.redsauce.net/de/cves/CVE-2026-73507","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73507","el":"https://www.redsauce.net/el/cves/CVE-2026-73507"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73507"}}
