CVE-2026-59243 - Apache Airflow FAB provider: FAB auth manager: JWT signature verification disabled by default for Azure AD OAuth (`verify_signature` defaults to `False`)
CVE ID :CVE-2026-59243
Published : July 29, 2026, 10:16 a.m. | 2 hours, 42 minutes ago
Description :The FAB auth manager's Azure AD OAuth login defaulted `verify_signature=False` when decoding the ID token, so an attacker able to present a forged or unsigned (`alg:none`) ID token to the OAuth callback could bypass authentication and log in as an arbitrary user, including one holding the Admin role (CWE-347). Deployments running the FAB auth manager with the Azure AD OAuth login path under its default configuration are affected; the Authentik path already defaulted to `True`. This issue affects `apache-airflow-providers-fab` before 3.7.3. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.3, which defaults `verify_signature=True`.

CVE-2026-12895 - SQL Injection in Frappe's ERPNext
CVE ID :CVE-2026-12895
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :SQL injection in Frappe'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.

CVE-2026-14488 - Meta Box AIO <= 3.8.0 - Missing Authorization to Unauthenticated Arbitrary Post Deletion via 'rwmb_frontend_field_object_id' Parameter
CVE ID :CVE-2026-14488
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :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.

CVE-2026-14900 - Cost Calculator Builder PRO <= 4.0.3 - Unauthenticated Remote Code Execution via 'orderDetails' Parameter
CVE ID :CVE-2026-14900
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :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.

CVE-2026-18220 - Binutils: binutils: out-of-bounds write in bfd dlx elf backend relocation processing
CVE ID :CVE-2026-18220
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :An out-of-bounds write vulnerability was found in the BFD library'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-2026-50642 - Terminal Escape Injection in diff‑so‑fancy
CVE ID :CVE-2026-50642
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :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

This issue has been fixed in the commit 9c81294

CVE-2026-56389 - Arbitrary Command Execution in GNU Bison
CVE ID :CVE-2026-56389
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :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.

CVE-2026-56390 - Arbitrary Output Location Change in GNU Bison
CVE ID :CVE-2026-56390
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :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-2026-5060 - MasterStudy LMS WordPress Plugin – for Online Courses and Education <= 3.7.14 - Insecure Direct Object Reference to Authenticated (Instructor+) Arbitrary Attachment Deletion
CVE ID :CVE-2026-5060
Published : July 29, 2026, 11:16 a.m. | 1 hour, 42 minutes ago
Description :The MasterStudy LMS WordPress Plugin – for Online Courses and Education plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.14. This is due to the `stm_lms_delete_cover()` function lacking ownership validation on the `file_id` parameter before passing it to `wp_delete_attachment()`. This makes it possible for authenticated attackers, with Instructor-level access and above, to delete arbitrary attachments belonging to any user by enumerating sequential attachment IDs.
Severity: 6.5 | MEDIUM
