Overview

Apache Thrift Lua bindings contain an inefficient algorithmic complexity flaw that can lead to excessive resource consumption. The vulnerability exists in all Thrift releases prior to 0.25.0. Upgrading to 0.25.0 or later mitigates the issue.

Description

Inefficient Algorithmic Complexity vulnerability in Apache Thrift Lua bindings. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

Impact

The flaw can cause denial of service by exhausting CPU or memory resources, compromising availability. Attackers may target services using Lua bindings, affecting any organization running legacy Thrift servers. Defenders should monitor for abnormal CPU spikes and restrict access to Thrift endpoints.

Remediation

Upgrade Apache Thrift to version 0.25.0 or later. If upgrade is not immediately possible, disable or remove Lua bindings from the Thrift service and restrict external access to the affected endpoints.

Risk context

High severity (CVSS 7.5/8.7) indicates significant risk; however, no EPSS data is available. Defenders should treat this as a high-priority issue and act promptly.

CVE-2026-104912

MISP before v2.5.48 has an authorization flaw in correlation handling during attribute searches. Correlated attributes and events can be authorized using a stale distribution snapshot instead of the live event access control list. This matters because restricted or unpublished events may remain visible to authenticated users who no longer have permission.

CVE-2026-94544

CVE-2026-94544 exposes a cache sharing flaw in Next.js 16.3.0‑16.3.8 that allows unauthenticated users to see unpublished draft content or see published content in draft mode. The vulnerability arises when Cache Components or experimental.useCache are enabled and cached functions return draft‑dependent data. It can lead to accidental disclosure of sensitive content on public sites.

CVE-2026-96270

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_id' parameter in all versions up to, and including, 2.13.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload is stored in the registering user's 'submitted' usermeta via update_user_meta() and is only triggered when an administrator opens the affected user record in the wp-admin Users modal, which inserts the unescaped output via jQuery .html().

CVE-2026-92977

The Real Cookie Banner: GDPR & ePrivacy Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment in all versions up to, and including, 5.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Malicious script payloads placed in the title attribute of an anchor tag survive WordPress's comment kses filter at save time, as the payload is only promoted to executable HTML attributes when the plugin's page-wide regex strips the closing quote delimiter at render time; exploitability is therefore subject to the standard comment moderation workflow before the comment is publicly displayed.
