    A code execution issue in the Java integration in Apache OpenOffice v4.1.16 and earlier allows a crafted untrusted document to trigger executing arbitrary (even remote) code when opened by the user. This issue is expected to be fixed in version 4.1.17, which is in the release candidate phase. Until then, users can mitigate this issue by disabling Java runtime integration in the Preferences dialog. This prevents the attack. If this is not possible, or as an extra precaution, you can avoid opening open untrusted files entirely. Once 4.1.17 is released, upgrade to that version to fix the issue.

  • Oct 2, 2026In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being CVE-2026-17508 · Other software · Legion of the Bouncy Castle Inc. · reported by 91579145-5d7b-4cc5-b925-a0262ff19630Medium 5.3

    In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could reject it. The affected paths are the RFC 9579 PBMAC1 MAC calculator builders, which took the PBKDF2 iteration count and derived-key length straight out of PBMAC1Params (JcePBMac1CalculatorBuilder, and PKCS12PBEUtils.createPBMac1Calculator reached from PKCS12PfxPdu.isMacValid); the scrypt parallelization parameter p in the PKCS#8 and PKCS#12 cost guards, which bounded only the cost parameter N and the block size r even though the scratch buffer scales with r times p, so the configured memory ceiling could be evaded entirely; the raw JCA PBKDF2 provider (org.bouncycastle.jcajce.provider.symmetric.PBEPBKDF2); and the bcrypt round count read from an encrypted OpenSSH v1 private key's own kdfoptions. Each now bounds the parameter before deriving, in line with the caps already applied elsewhere in the tree, with the OpenSSH round count configurable through the new org.bouncycastle.openssh.max_r

    Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data. A deserialization weakness in Kiteworks Core could, under certain conditions, allow crafted data to be deserialized unsafely, potentially resulting in remote code execution on the appliance. Exploitation depends on an attacker first being able to influence the affected data, so this issue is not exploitable on its own.

    Kobako is a Ruby gem that embeds a Wasm-isolated mruby interpreter inside applications, allowing execution of untrusted Ruby scripts (LLM-generated code, user formulas, student submissions, third-party plugins) in-process without giving them access to host memory, files, network, or credentials. From version 0.1.0 to before version 0.9.1, a guest mruby script running inside the Kobako sandbox can execute arbitrary Ruby in the host process, fully escaping the sandbox. This issue has been patched in version 0.9.1.

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.
