TECHNICAL SUMMARY Strapi contains a cleartext storage of sensitive information vulnerability that could allow attackers with access to the admin panel to discover sensitive user details via the query filter. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version.
WHY THIS VERDICT Attacks are confirmed, but the vulnerability is more than a year old and we see no ransomware use, public attack tools, internet-facing product, critical severity or high prediction score. Check whether it applies to you.
WHY IT RANKS HERE Exploitation is confirmed by an authoritative source.

04 EXPLOITED
■ CONFIRMEDNEWEST EVIDENCE · 2 INDEPENDENT SOURCESStrapi contains a cleartext storage of sensitive information vulnerability that could allow attackers with access to the admin panel to discover sensitive user details via the query filter. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version. This vulnerability can be chained with CVE-2023-22621 to achieve remote code execution. CISA Vulnrichment marks CVE-2023-22894 as actively exploited.

- Do we run Strapi? If yes, is it patched or cut off from the internet?
- Who owns fixing it, and by what date?
- Have we checked for signs of attack since the first report, not just since the patch?
