In versions 1.4.0 and below, improper input handling in the JSON deserialization component can lead to arbitrary JavaScript code execution. Exploitation is possible via overriding constant value and error deserialization, allowing indirect access to unsafe JS evaluation. At minimum, attackers need the ability to perform 4 separate requests on the same function, and partial knowledge of how the serialized data is used during later runtime processing. This vulnerability affects the fromJSON and fromCrossJSON functions in a client-to-server transmission scenario. This issue has been fixed in version 1.4.0.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-23737","url":"https://www.suse.com/security/cve/CVE-2026-23737"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1257096 for CVE-2026-23737","url":"https://bugzilla.suse.com/1257096"}],"title":"SUSE CVE CVE-2026-23737","tracking":{"current_release_date":"2026-01-23T00:24:50Z","generator":{"date":"2026-01-23T00:24:50Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-23737","initial_release_date":"2026-01-23T00:24:50Z","revision_history":[{"date":"2026-01-23T00:24:50Z","number":"2","summary":"references added,severity changed from  to important"}],"status":"interim","version":"2"}}}
