CVE-2024-41809Network attack vector

Browser script execution via unsanitized subscription errors

Published Jul 25, 2024 · Updated Aug 12, 2024

Cross-site scripting in OpenObserve before 0.10.0 allows remote attackers to execute script through a crafted subscription error. MemberSubscription.vue passes a nonempty error value directly to Vue's v-html directive, causing the browser to interpret the value as markup without sanitization. Exposure requires the member-subscription error path to render attacker-influenced HTML; resulting script executes in the viewing browser's OpenObserve origin.
