CVE-2026-35468 MEDIUM This Month

Denial of service in Nimiq Core RS Albatross prior to version 1.3.0 allows remote attackers to crash full nodes by sending specially crafted consensus requests (RequestTransactionsProof or RequestTransactionReceiptsByAddress) when the node is operating without a history index. The vulnerability stems from unsafe unwrap() calls that panic when encountering a valid but unindexed state, affecting nodes during synchronization or when intentionally configured without history indexing.

CVE-2026-31830 HIGH PATCH This Week

Sigstore-ruby versions before 0.2.3 fail to properly validate artifact digests when verifying DSSE bundles with in-toto attestations, causing the library to incorrectly return successful verification even when the artifact does not match the attested subject. This allows attackers to bypass cryptographic verification controls and accept mismatched or tampered artifacts as valid. Organizations using sigstore-ruby for supply chain verification should upgrade to version 0.2.3 immediately, though no patch is currently available for other affected projects.

GitLab CE/EE versions 18.6 before 18.6.4, 18.7 before 18.7.2, and 18.8 before 18.8.2 are vulnerable to two-factor authentication bypass when an attacker has knowledge of a victim's credential ID and can forge device responses. This allows an unauthenticated attacker to circumvent 2FA protections and gain unauthorized access to accounts. No patch is currently available.

CVE-2026-21920 HIGH This Week

Denial-of-service attacks against Juniper SRX Series devices running Junos OS 23.4 through 24.4 can be triggered remotely by sending a maliciously crafted DNS request, causing the flowd process to crash and interrupt service until recovery completes. The vulnerability stems from an unchecked return value in the DNS module that allows unauthenticated, network-based attackers to exploit DNS-enabled SRX configurations without any user interaction. No patch is currently available for affected versions.

CVE-2026-0421 MEDIUM This Month

Secure Boot bypass in iOS allows local privileged users to disable Secure Boot protections even when explicitly configured as enabled in BIOS, affecting systems with Secure Boot set to User Mode. An attacker with high-level system access and user interaction can circumvent boot-time security protections, potentially enabling unsigned code execution. No patch is currently available for this medium-severity vulnerability.
