CVE-2026-33900

In multiple locations, there is a possible way to achieve code execution due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

jq is a command-line JSON processor. An integer overflow vulnerability exists through version 1.8.1 within the jvp_string_append() and jvp_string_copy_replace_bad functions, where concatenating strings with a combined length exceeding 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, resulting in a drastically undersized heap buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap buffer overflow classified as CWE-190 (Integer Overflow) leading to CWE-122 (Heap-based Buffer Overflow). Any system evaluating untrusted jq queries is affected, as an attacker can crash the process or potentially achieve further exploitation through heap corruption by crafting queries that produce extremely large strings. The root cause is the absence of string size bounds checking, unlike arrays and objects which already have size limits. The issue has been addressed in commit e47e56d226519635768e6aab2f38f0ab037c09e5.

A vulnerability was identified in uclouvain openjpeg up to 2.5.4. This impacts the function opj_pi_initialise_encode in the library src/lib/openjp2/pi.c. The manipulation leads to integer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is 839936aa33eb8899bbbd80fda02796bb65068951. It is suggested to install a patch to address this issue.

Memory corruption while using alignments for memory allocation.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.

A security vulnerability has been detected in EIPStackGroup OpENer up to 2.3.0. Affected is the function CreateMessageRouterRequestStructure of the file cipmessagerouter.c of the component SendRRData Handler. The manipulation leads to use after free. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.

A security vulnerability has been detected in SourceCodester Online Boat Reservation System 1.0. Affected by this vulnerability is an unknown functionality of the component Administrative Endpoint. The manipulation leads to improper authorization. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. Multiple endpoints are affected.

The EmergencyWP – Dead Man's switch & legacy deliverance plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.2. This is due to missing or incorrect nonce validation on the form_settings_ui (settings save handler, procedural include scope) function. This makes it possible for unauthenticated attackers to modify plugin settings including the minimum access role (altering WordPress role capabilities via add_cap/remove_cap), the data-erasure-on-uninstall flag, life-check timing values, the mandator email address, the confirmation page ID, and date/time formats via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Passeum Ticketing plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.0. This is due to the `get_shop_url()` method returning the `shop_name` setting value without sanitization when it begins with "http", combined with insufficient validation in the `validate_shop_name()` function which only checks for empty values and string type. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary external scripts by setting the `shop_name` to an attacker-controlled URL (e.g., `https://attacker.com`), which causes the plugin to enqueue external JavaScript and CSS from the attacker-controlled domain via `wp_register_script()` and `wp_register_style()`. The injected scripts execute on every frontend page containing any Passeum Ticketing shortcode, affecting all site visitors. Please note that this does not affect single-site installations as administrators already have the `unfiltered_html` capability.

A weakness has been identified in johnhuang316 code-index-mcp up to 2.14.0. Affected is the function is_safe_regex_pattern of the component search_code_advanced. Executing a manipulation of the argument regex can lead to inefficient regular expression complexity. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.14.1 is able to address this issue. This patch is called 25bc02fac74051ddae15ce79e952f00211b1ea6b. Upgrading the affected component is recommended.
