CVE-2025-29847
HighSummary
Vulnerability in Apache Linkis. When using the JDBC engine and data source functionality, if the URL parameter configured on the frontend has undergone multiple rounds of URL encoding, it may bypass the system's checks. This can allow unauthorized access to system files via JDBC parameters. Affects versions from 1.3.0 through 1.7.0.
Risk Assessment
An attacker may gain unauthorized access to system files, potentially leading to exposure of sensitive data or further system compromise.
Recommendation
Upgrade Apache Linkis to version 1.8.0, which fixes the issue. Additionally, check if connection information contains the '%' character and perform URL decoding.

The Botiga Pro WordPress plugin before 1.6.5 does not perform any authorisation checks on one of its REST routes, allowing unauthenticated users to update arbitrary WordPress options with arbitrary values, which could lead to privilege escalation and a full site takeover. The same route also allows unauthenticated users to store arbitrary web scripts which are then executed on every page of the site's front end, as well as to move arbitrary posts to the trash.

- CVE-2026-92229Critical
The Forminator Forms plugin for WordPress (versions up to and including 1.57.2) is vulnerable to arbitrary shortcode execution. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
- CVE-2026-89274Critical
The WP Recipe Maker plugin for WordPress (versions up to and including 10.8.1) is vulnerable to arbitrary shortcode execution. The sanitize_metadata() function recursively calls do_shortcode() on recipe metadata fields, including reviewBody populated from comment content, without sanitizing shortcode tokens before execution. Unauthenticated attackers can execute arbitrary registered shortcodes on every recipe page render, disclosing data in JSON-LD metadata.
- CVE-2026-84434Critical
The Gravity Forms plugin for WordPress (versions up to and including 3.1.0.4) is vulnerable to arbitrary file upload via the upload_file function. A mismatch between validation and persistence pipelines allows hidden file upload fields to bypass extension validation. Unauthenticated attackers can upload executable files, enabling remote code execution.

- CVE-2026-75885Critical
A flaw was found in the OpenShift console allowing unauthenticated access to the /api/devfile/ and /api/devfile/samples/ endpoints. A remote attacker can send crafted devfile payloads, leading to Server-Side Request Forgery (SSRF) and, by sending repeated large requests without a specified content length, to unbounded memory growth and Denial of Service (DoS).
