Low risk4th percentile - higher than 4% of all known CVEs
Summary
The Rabbit Hole plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. Missing or incorrect nonce validation on the plugin's reset functionality allows an unauthenticated attacker to reset the plugin's settings if they trick a site administrator into clicking a crafted link; the vulnerability is exacerbated by the reset being performed via a GET request, making exploitation trivial via image tags or hyperlinks.
Risk Assessment
An attacker can reset the plugin's settings without the administrator's knowledge, leading to loss of configuration and potential site malfunction. The risk is high because exploitation is very easy (just an image or link).
Recommendation
Update the Rabbit Hole plugin to a version newer than 1.1 as soon as it becomes available, and consider disabling it in the meantime. Additionally, enforce least privilege and educate administrators not to click unknown links.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
The Rabbit Hole plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing or incorrect nonce validation on the plugin's reset functionality. This makes it possible for unauthenticated attackers to reset the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The vulnerability is exacerbated by the fact that the reset operation is performed via a GET request, making exploitation trivial via image tags or hyperlinks.
