*** Pendiente de traducción *** The Booking System Trafft plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `bookingWebsiteUrl` setting in all versions up to, and including, 1.0.17 due to a missing capability check on the `set_options` AJAX action when the plugin is operating in agency mode. The `trafftSetOptions()` handler verifies a nonce that is exposed to any authenticated user (it is printed inline on every admin page, including profile.php) but performs no capability check before calling `update_option(&#39;trafft_option&#39;, [&#39;bookingWebsiteUrl&#39; => ...])`. This setting is then used by `trafftAdminAssets()` to enqueue `/embed.js` as a script on every front-end page that renders the booking shortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to point the embed-script URL at an attacker-controlled origin and execute arbitrary JavaScript in the browser of every site visitor (including admins).

*** Pendiente de traducción *** The Klubraum Membership Request plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `kr_mr_store_settings()` function in all versions up to, and including, 1.1.0. This makes it possible for unauthenticated attackers to update the plugin&#39;s settings, including the Klubraum API token and introduction text, effectively hijacking the plugin&#39;s integration with the Klubraum service.

CVE-2026-18220

Fecha de publicación:

29/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** An out-of-bounds write vulnerability was found in the BFD library&#39;s DLX ELF backend (bfd/elf32-dlx.c) in GNU binutils. The dlx_rtype_to_howto() function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values (via ELF32_R_TYPE(r_info)) before indexing into the dlx_elf_howto_table[] array. The DLX relocation type number space is non-contiguous (basic types 0-6, extended types at 0x10000+), but the default case in the switch statement allows arbitrary index values to reach the array access. A specially crafted ELF/DLX object file can trigger this out-of-bounds write when processed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). The vulnerability has been demonstrated to achieve arbitrary code execution via a File Stream Oriented Programming (FSOP) attack against glibc FILE structures (stderr), redirecting control flow to system(). Attack scenarios include CI/CD pipelines performing automated binary analysis, developer workstations running objdump/readelf on untrusted binaries, automated security scanning or malware analysis tools invoking binutils, and package build systems processing third-party code. Note: This vulnerability is only exploitable when binutils is built with the DLX backend enabled (typically via --enable-targets=all).

CVE-2026-56389

Fecha de publicación:

Idioma:

Inglés

*** Pendiente de traducción *** GNU Bison allows for an execution of an arbitrary program during HTML report generation due to improper handling of grammar-defined configuration variables. A grammar file can override the executable used for the XML‑to‑HTML transformation step via %define tool.xsltproc, which is accepted without restriction and passed directly to execvp(). When running bison --html on a attacker-provided grammar, this behavior allows execution of an arbitrary program with the privileges of the Bison process. Maintainers of this project were notified about this vulnerability, and fixed the issue in commit 3169c1e7a2c6acc4c59dfcf8b089896d6881925b. However, they did not provide vulnerable version range. Version 3.8.2 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

*** Pendiente de traducción *** GNU Bison improperly handles grammar‑defined output paths. Grammar directives such as %output and %header allow specifying file paths, which are accepted without restriction and override caller‑supplied output options. When processing attacker-supplied grammar, this behavior allows directing generated files to arbitrary writable locations on the filesystem, potentially overwriting existing files accessible to the Bison process. Maintainers of this project were notified about this vulnerability, and fixed the issue in commit 8d101c19d4d9aaedf83a448c925513742d4efcf0. However, they did not provide vulnerable version range. Version 3.8.2 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

CVE-2026-50642

Fecha de publicación:

29/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** diff‑so‑fancy does not properly sanitize non‑SGR terminal control sequences before outputting diff data. The application only strips ANSI SGR sequences while allowing other control characters, including carriage return (\r) and escape sequences (e.g., OSC, CSI), to pass through unsanitized. An attacker can embed malicious control sequences in filenames, diff metadata, or file content that are rendered directly in the terminal during diff viewing. This can lead to output manipulation, including filename spoofing, terminal screen clearing, and clipboard injection via supported escape sequences. Successful exploitation may mislead users during code review, alter terminal state, or result in unintended command execution through clipboard hijacking. This issue has been fixed in the commit 9c81294

CVE-2026-14488

Fecha de publicación:

Idioma:

Inglés

*** Pendiente de traducción *** The Meta Box AIO plugin for WordPress is vulnerable to Missing Authorization via the template_redirect dispatcher in the MB Frontend Submission extension in versions up to, and including, 3.8.0. This is due to the handle_request() function routing the mbfs_delete action without any capability or ownership check, and the nonce verification in check_ajax() being gated behind is_ajax() which is false for template_redirect requests, making it bypassable. This makes it possible for unauthenticated attackers to delete arbitrary posts and pages by supplying an attacker-controlled post ID via the rwmb_frontend_field_object_id GET parameter on any page that hosts a frontend submission form regardless of whether allow_delete is enabled.

*** Pendiente de traducción *** The Cost Calculator Builder PRO plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.3 via the js_to_php function. This is due to insufficient sanitization of the orderDetails[*].originalValue field, which is injected verbatim into a calculator formula string passed to PHP eval() inside js_to_php(), with the regex allow-list in evaluateFormula() only filtering alphanumeric tokens and leaving non-word punctuation characters intact. This makes it possible for unauthenticated attackers to execute code on the server. The only authentication barrier is a nonce check, but the required nonce is publicly emitted on every front-end page via the wp_head hook, making it freely obtainable by unauthenticated visitors. Payloads must be non-word XOR gadgets to bypass sanitization.

*** Pendiente de traducción *** The GTM4WP – A Google Tag Manager (GTM) plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via WooCommerce Billing Fields in all versions up to, and including, 1.22.3 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. This requires the GTM4WP WooCommerce order data integration option (GTM4WP_OPTION_INTEGRATE_WCORDERDATA) to be enabled, and is exploited by placing a guest checkout order with a JavaScript payload in a WooCommerce billing field such as the billing first name.

CVE-2026-12895

Fecha de publicación:

29/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** SQL injection in Frappe&#39;s ERPNext, versions ERPNext 15.107.0 and Frappe 15.107.2. The application constructs SQL queries through direct string interpolation using `str.format()` without employing parameterized queries, allowing the name (docname) of a Supplier record containing SQL metacharacters to be interpreted as part of the query. Exploitation of this vulnerability could allow an authenticated user with low privileges to execute arbitrary SQL queries, bypass Frappe’s access restrictions (DocPerm), extract confidential information from the database—including fragments of the administrator’s password hash—and access other sensitive data, such as credentials, integration tokens, or financial information.
