Credential leakage in the Perl HTTP::Tiny client (all versions before 0.095) lets an attacker who controls a redirect destination harvest sensitive headers. When a server answers with a 3xx redirect, HTTP::Tiny re-sends caller-supplied Authorization, Cookie and Proxy-Authorization headers to the new host without verifying it shares the original origin, including across scheme, host or port boundaries and over https-to-http downgrades that expose them in cleartext on the wire. No public exploit is identified at time of analysis and CISA SSVC rates exploitation as none, but the flaw is well-documented and a vendor patch is available in 0.095.
HTTP::Tiny versions before 0.093 for Perl fail to validate carriage return and line feed (CRLF) characters in HTTP request lines and header values, allowing attackers who control input URLs or headers to inject additional HTTP headers and smuggle requests to upstream servers. Remote unauthenticated attackers can exploit this via crafted URLs passed to webhook or URL fetch endpoints, achieving limited information disclosure and integrity compromise. EPSS score of 0.03% (percentile 7%) indicates low practical exploitation probability despite network-vector accessibility.
HTTP::Session versions through 0.53 for Perl defaults to using insecurely generated session ids.
HTTP::Session2 versions through 1.09 for Perl does not validate the format of user provided session ids, enabling code injection or other impact depending on session backend. [CVSS 6.5 MEDIUM]
Denial of service against HTTP/2 server implementations allows remote unauthenticated attackers to exhaust server resources by rapidly opening and immediately canceling (RST_STREAM) large numbers of streams over a single connection, a technique dubbed the 'Rapid Reset' attack. The flaw is confirmed actively exploited (CISA KEV) following large-scale weaponization observed August through October 2023, with publicly available exploit code and an EPSS score of 94.45% placing it in the 100th percentile for likelihood of exploitation. Virtually every major HTTP/2 stack - including nghttp2, Netty, Envoy, and Eclipse Jetty - is affected.
react/http is an event-driven, streaming HTTP client and server implementation for ReactPHP. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Uncontrolled Resource Consumption vulnerability could allow attackers to cause denial of service by exhausting system resources.
ReactPHP HTTP is a streaming HTTP client and server implementation for ReactPHP. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
An issue was discovered in the http package through 0.12.2 for Dart. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
An issue was discovered in the http crate before 0.1.20 for Rust. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
