Know what's exploited today. Act before it hits you.
Stay informed about critical vulnerabilities, actively exploited CVEs, vendor advisories, and emerging cyber risks. R4IM continuously monitors trusted public sources and simplifies the actions organizations should take.
When a libcurl-based application performs transfers via `SCP://` or `SFTP://` and utilizes the `CURLOPT_SSH_KEYFUNCTION` call…
When a libcurl-based application performs transfers via `SCP://` or `SFTP://` and utilizes the `CURLOPT_SSH_KEYFUNCTION` callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for that host in the `known_hosts` file. Instead of rejecting the mismatch, the callback mechanism fails to properly enforce the restriction, allowing the connection to succeed without warning and risking a potential man-in-the-middle attack.
A vulnerability in libcurl caused the HTTP `Referer:` header to persist even when explicitly cleared.
A vulnerability in libcurl caused the HTTP `Referer:` header to persist even when explicitly cleared. While the documentation states that passing NULL to `CURLOPT_REFERER` suppresses the header, the option failed to clear the internal state. As a result, the previous referrer string was erroneously reused and sent in subsequent requests, potentially leaking sensitive information to unintended servers.
In this scenario, libcurl first uses a proper HTTP/3 server for the initial transfers, and when it makes a second transfer to…
In this scenario, libcurl first uses a proper HTTP/3 server for the initial transfers, and when it makes a second transfer to the same site it has been replaced by the attacker's impostor machine - without a valid certificate. When libcurl returns to the hostname the second time with a cached SSL session (`CURLOPT_SSL_SESSIONID_CACHE` is not disabled) and early data enabled (the `CURLSSLOPT_EARLYDATA` bit is set in `CURLOPT_SSL_OPTIONS`), libcurl might send off the second request's bytes on that new connection *before* enforcing the certificate verification failure. Potentially leaking sensitive information.

Calling `curl_easy_pause()` within the event-based `CURLMOPT_SOCKETFUNCTION` callback triggers a use-after-free vulnerability, where libcurl attempts to store a flag using a dangling struct pointer immediately after that pointer's memory has been freed.

libcurl had a flaw that when instructed to clear proxy authentication credentials which made it not do so, leaving the old credentials around to get used for subsequent transfers that should not know nor use them.
A vulnerability has been found in GPAC up to f1219cde.
A vulnerability has been found in GPAC up to f1219cde. This issue affects the function gf_url_concatenate_ex of the file utils/url.c of the component URL Handler. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. Upgrading to version abi-16.23 is capable of addressing this issue. The identifier of the patch is afca1f1181668d85941d51ed1adf647807d5d975. It is advisable to upgrade the affected component.
