|---|---|---|---|
| 2024-11-06 | CVE-2024-9681 | Incorrect Comparison vulnerability in Haxx Curl 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. | 6.5 |
| 2023-12-07 | CVE-2023-46218 | This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. | 6.5 |
| 2023-05-26 | CVE-2023-28319 | Use After Free vulnerability in multiple products A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH server's public key using a SHA 256 hash. | 7.5 |
| 2023-05-26 | CVE-2023-28320 | Resource Exhaustion vulnerability in multiple products A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time. | 5.9 |
| 2023-05-26 | CVE-2023-28321 | Improper Certificate Validation vulnerability in multiple products An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. | 5.9 |
| 2023-05-26 | CVE-2023-28322 | An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. | 3.7 |
| 2023-03-30 | CVE-2023-27533 | Injection vulnerability in multiple products A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. | 8.8 |
| 2023-03-30 | CVE-2023-27534 | Path Traversal vulnerability in multiple products A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. | 8.8 |
| 2023-02-23 | CVE-2023-23914 | Cleartext Transmission of Sensitive Information vulnerability in multiple products A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. | 9.1 |
| 2023-02-23 | CVE-2023-23915 | Cleartext Transmission of Sensitive Information vulnerability in multiple products A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. | 6.5 |
