CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 0CVE-2022-39236 – Matrix Javascript SDK improper beacon events can cause availability issues
https://notcve.org/view.php?id=CVE-2022-39236
Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Starting with version 17.1.0-rc.1, improperly formed beacon events can disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This is patched in matrix-js-sdk v19.7.0. Redacting applicable events, waiting for the sync processor to store data, and restarting the client are possible workarounds. • https://github.com/matrix-org/matrix-js-sdk/commit/a587d7c36026fe1fcf93dfff63588abee359be76 https://github.com/matrix-org/matrix-js-sdk/releases/tag/v19.7.0 https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-hvv8-5v86-r45x https://github.com/matrix-org/matrix-spec-proposals/pull/3488 https://security.gentoo.org/glsa/202210-35 https://access.redhat.com/security/cve/CVE-2022-39236 https://bugzilla.redhat.com/show_bug.cgi?id=2135391 • CWE-20: Improper Input Validation •
CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2022-36059 – Prototype pollution in matrix-js-sdk
https://notcve.org/view.php?id=CVE-2022-36059
matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 19.4.0 events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This issue has been fixed in matrix-js-sdk 19.4.0 and users are advised to upgrade. Users unable to upgrade may mitigate this issue by redacting applicable events, waiting for the sync processor to store data, and restarting the client. • https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-rfv9-x7hh-xc32 https://access.redhat.com/security/cve/CVE-2022-36059 https://bugzilla.redhat.com/show_bug.cgi?id=2123258 • CWE-440: Expected Behavior Violation CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
