  script_tag(name:"insight", value:"When doing multi-threaded LDAPS transfers (LDAP over TLS) with libcurl,changing TLS options in one thread would inadvertently change them globally and therefore possibly also affect other concurrently setup transfers.Disabling certificate verification for a specific transfer could unintentionally disable the feature for other threads as well.(CVE-2025-14017)

When an OAuth2 bearer token is used for an HTTP(S) transfer, and that transfer performs a cross-protocol redirect to a second URL that uses an IMAP, LDAP,POP3 or SMTP scheme, curl might wrongly pass on the bearer token to the new target host.(CVE-2025-14524)

When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent.(CVE-2025-15224)

When doing SSH-based transfers using either SCP or SFTP, and setting the known_hosts file, libcurl could still mistakenly accept connecting to hosts *not present* in the specified file if they were added as recognized in the libssh *global* known_hosts file.(CVE-2025-15079)

curl's code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms.This prevents curl from detecting MITM attackers and more.(CVE-2025-10966)

1. A cookie is set using the `secure` keyword for `https://target` 2. curl is redirected to or otherwise made to speak with `http://target` (same hostname, but using clear text HTTP) using the same cookie set 3. The same cookie name is set - but with just a slash as path (`path=\'/\',`). Since this site is not secure, the cookie *should* just be ignored. 4. A bug in the path comparison logic makes curl read outside a heap buffer boundary The bug either causes a crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site override the contents of the secure cookie, contrary to expectations and depending on the memory contents immediately following the single-byte allocation that holds the path. The presumed and correct behavior would be to plainly ignore the second set of the cookie since it was already set as secure on a secure host so overriding it on an insecure host should not be okay.(CVE-2025-9086)");
