Threats Tagged 'cve-2026-87863'

CVE-2026-87863 is a vulnerability where an authenticated HTTPS origin can supply an HSTS max-age value that the parser accepts, but later fails during time serialization. On 64-bit systems, extremely large max-age values cause expiry times that exceed calendar time structure limits. This leads to cache save operations truncating the original HSTS file and deleting the temporary replacement file, resulting in an empty or partial HSTS cache. The error is silently ignored, causing curl to exit successfully despite data loss.

Red Hat Discovery, also known as Discovery, is an inspection and reporting tool that finds, identifies, and reports environment data, or facts, such as the number of physical and virtual systems on a network, their operating systems, and relevant configuration data stored within them. Discovery also identifies and reports more detailed facts for some versions of key Red Hat packages and products that it finds in the network.
