An attacker can run an Owner-installed malicious module that writes output without newlines, crashing the server and denying service to all namespaces and databases.","cvssScore":4.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-jj89-wvrw-c4gp","tags":[]},{"url":"https://www.vulncheck.com/advisories/surrealdb-3.1.0-before-3.3.0-memory-exhaustion-via-surrealism-module-output-buffering","tags":[]}],"exploitRefs":[{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-jj89-wvrw-c4gp","tags":[]}],"hasPoc":true,"ai":null}
