| CVE-2019-20454 | Hig | 0.42 | 7.5 | 0.02 | Feb 14, 2020 | An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash… | ||
| CVE-2022-43552 | Med | 0.39 | 5.9 | 0.03 | Feb 9, 2023 | A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl… | ||
| CVE-2022-32208 | Med | 0.39 | 5.9 | 0.07 | Jul 7, 2022 | When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. | ||

| CVE-2022-30115 | Med | 0.28 | 4.3 | 0.01 | Jun 2, 2022 | Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the… | ||
