01 Jun 2022 — libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then wo... • https://hackerone.com/reports/1553301 • CWE-201: Insertion of Sensitive Information Into Sent Data •

01 Jun 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 HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. usando su soporte HSTS, curl puede ser instruido para usar HTTPS directamente en lugar de usar un paso no ... • http://www.openwall.com/lists/oss-security/2022/10/26/4 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

11 May 2022 — The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.

15 Sep 2021 — When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-thro... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-310: Cryptographic Issues CWE-319: Cleartext Transmission of Sensitive Information CWE-345: Insufficient Verification of Data Authenticity •
