  • Jul 13, 2026Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.CVE-2026-57433 · Other software · HAARG · reported by 9b29abf9-4ab0-4765-b253-1875cd9b441eCritical 9.8

    Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record. retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value. A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.

    Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID. These are predictable or low-entropy sources that are unsuitable for security purposes.

    Storable versions before 3.05 for Perl has a stack overflow. The retrieve_hook function stored the length of the class name into a signed integer but in read operations treated the length as unsigned. This allowed an attacker to craft data that could trigger the overflow.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
