Summary
The Ninja Popups plugin (versions up to and including 4.7.8) contains a Stored Cross-site Scripting (XSS) vulnerability due to improper neutralization of input during web page generation. A malicious script can be persistently stored and executed in the user's browser.
Risk Assessment
An attacker could inject a persistent malicious script that executes in the browsers of site visitors or administrators. This may lead to session theft, account takeover, or website content modification.
Recommendation
Update the Ninja Popups plugin to a version newer than 4.7.8 once a fix is available. Also check the site content for any injected malicious scripts.

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.
