When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects curl using applications that enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS cache either needs to have been populated manually or there needs to have been previous HTTPS accesses done as the cache needs to have entries for the domains involved to trigger this problem.) When `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different period of time than what was asked for by the origin server. If `example.com` for example stops supporting HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set) timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently switch back to insecure HTTP earlier than otherwise intended. Cuando se le pide a curl que use HSTS, el tiempo de expiración de un subdominio puede sobrescribir la entrada de caché de un dominio principal, lo que hace que finalice antes o después de lo previsto. Esto afecta a curl que usa aplicaciones que habilitan HSTS y usan URL con el esquema inseguro `HTTP://` y realizan transferencias con hosts como `x.example.com` así como `example.com` donde el primer host es un subdominio del segundo host. • https://curl.se/docs/CVE-2024-9681.html https://curl.se/docs/CVE-2024-9681.json https://hackerone.com/reports/2764830 •

When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate. • https://curl.se/docs/CVE-2024-8096.json https://curl.se/docs/CVE-2024-8096.html https://hackerone.com/reports/2669852 • CWE-295: Improper Certificate Validation •
