  • Sep 16, 2026A flaw was found in sequoia-openpgp.CVE-2026-42784 · Other software · Red Hat · reported by Red HatHigh 7.4

    A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.

  • Apr 3, 2026A flaw was found in rust-rpm-sequoia.CVE-2026-2625 · Other software · Red Hat · reported by Red HatMedium 4

    A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.

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.
