Denial-of-service in the Storable module for Perl (versions before 3.41) allows remote attackers to abort deserialization by supplying a crafted SX_HOOK record whose item count equals I32_MAX. The signed 32-bit count plus one wraps to a negative value, which av_extend rejects with a fatal panic, terminating any thaw() or retrieve() call on attacker-controlled data. No public exploit identified at time of analysis; despite the assigned CVSS of 9.8 (C:H/I:H/A:H), the documented outcome is a controlled abort rather than memory corruption or code execution.
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.
