CVE-2025-47187
HighSummary
Podatność w telefonach SIP serii Mitel 6800, 6900 i 6900w oraz jednostce konferencyjnej 6970 umożliwia nieautoryzowanemu atakującemu przeprowadzenie ataku polegającego na przesyłaniu plików z powodu braku mechanizmów uwierzytelniania. Udało się to dzięki możliwości przesyłania dowolnych plików WAV, co może prowadzić do wyczerpania pamięci telefonu.
Risk Assessment
Atakujący może wykorzystać tę podatność do zapełnienia pamięci telefonu, co może wpłynąć na jego wydajność, chociaż nie wpłynie na dostępność czy działanie urządzenia. Może to prowadzić do problemów z zarządzaniem i konserwacją urządzeń w organizacji.
Recommendation
Zaleca się aktualizację oprogramowania telefonów do najnowszej wersji, która zawiera poprawki zabezpieczeń, oraz wdrożenie mechanizmów uwierzytelniania dla przesyłania plików, aby zminimalizować ryzyko ataków.

The Paytium: Mollie payment forms & donations plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.0.3. The 5.0.3 patch added a signature gate on the pt-paytium-user-data field but left a second filter, pt_cf_checkout_meta(), that copies $_POST['pt_form_field'] values without signature verification, allowing the user role to be overwritten and an administrator account to be created.

GitLab CE/EE versions from 19.2 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 contain an integer overflow issue when compiling a specially crafted regular expression in a CI/CD configuration. Under certain conditions an authenticated user could execute arbitrary code on the GitLab server.

Laravel-Mediable versions 7.0.0 to 7.0.2 contain an incomplete patch for CVE-2026-49972 — the .pht extension is missing from the forbidden_extensions blocklist in config/mediable.php. Apache on Debian and Ubuntu executes .pht files as PHP, allowing an attacker to upload a malicious file and achieve remote code execution.
- CVE-2026-6928Critical
IBM Concert versions 1.0.0 through 3.0.0 references or accesses memory after it has been freed (use-after-free). An attacker who can influence program execution or input may exploit this condition to corrupt memory, cause application crashes, or execute arbitrary code.
- CVE-2026-6730Critical
IBM Concert versions 1.0.0 through 3.0.0 is vulnerable to a buffer overflow caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.
- CVE-2026-6721Critical
IBM Concert versions 1.0.0 through 3.0.0 allows an unauthenticated remote attacker to supply specially crafted input that is incorporated into OS commands, resulting in arbitrary command execution. Successful exploitation allows remote code execution with the privileges of the affected application.

RabbitMQ prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 — when no CA bundle is available, ssl_options/1 falls back to [{verify, verify_none}] with no warning. An attacker in a man-in-the-middle position can forge the JWKS response, leading the broker to accept arbitrary JWTs.
- CVE-2026-67231Critical
RabbitMQ prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 — the trust-store plugin installs a verify_fun that overrides {bad_cert, unknown_ca} / {bad_cert, selfsigned_peer} when the presented cert "matches" a whitelisted one. The match key relies solely on issuer name and serial number, which can be easily forged, allowing TLS client authentication bypass.
Original NVD description (English source)
A vulnerability in the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones through 6.4 SP4 (R6.4.0.4006), and the 6970 Conference Unit through 6.4 SP4 (R6.4.0.4006) or version V1 R0.1.0, could allow an unauthenticated attacker to perform a file upload attack due to missing authentication mechanisms. A successful exploit could allow an attacker to upload arbitrary WAV files, which may potentially exhaust the phone’s storage without affecting the phone's availability or operation.
