An attacker who can reach these endpoints may trigger cache operations without authentication, potentially leading to data loss, service disruption, or exposure of sensitive cache contents.

The EPSS score is below 1\u202f%, implying a very low likelihood of exploitation at present. The vulnerability is not listed in the CISA KEV catalogue, so no confirmed widespread exploitation has been reported. Attackers would need to discover and gain network access to the application, then issue the delete, purge, or sync requests. With no remediation detected once this analysis was written, the risk remains moderate until a patch or workaround is deployed."}}}}, "created": "2026-02-23T14:35:44.854838+00:00", "updated": "2026-04-17T17:30:23.862726+00:00", "vendors": ["yeqifu", "yeqifu$PRODUCT$warehouse"]}
