LAPSWebUI: Use of Web Browser Cache Containing Sensitive Information
CVE-2025-15554 is a high-severity use of web browser cache containing sensitive information vulnerability in LAPSWebUI from Truesec, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 2.4 as the first without the flaw, so updating LAPSWebUI to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Use of Web Browser Cache Containing Sensitive Information
The web application does not use an appropriate caching policy that specifies the extent to which each web page and associated form fields should be cached.
How developers prevent this class of flaw
- Use a restrictive caching policy for forms and web pages that potentially contain sensitive information, such as no-cache in the Cache-Control header.
- Do not store unnecessarily sensitive information in the cache.
