CVE-2025-54595
HighSummary
Pearcleaner to darmowa aplikacja do czyszczenia systemu macOS, która zawiera narzędzie pomocnicze PearcleanerHelper. W wersjach 4.4.0 do 4.5.1, narzędzie to rejestruje usługę XPC, która akceptuje nieautoryzowane połączenia z lokalnych procesów, co pozwala na wykonywanie dowolnych poleceń powłoki przez lokalnych użytkowników bez uprawnień.
Risk Assessment
Umożliwienie lokalnym użytkownikom bez uprawnień eskalacji do uprawnień roota stanowi poważne zagrożenie dla bezpieczeństwa systemu. Może to prowadzić do nieautoryzowanego dostępu do wrażliwych danych i zasobów systemowych.
Recommendation
Zaleca się aktualizację aplikacji Pearcleaner do wersji 4.5.2, aby usunąć tę podatność. Należy również monitorować i ograniczać dostęp do narzędzi pomocniczych, które mogą mieć podwyższone uprawnienia.

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.
- CVE-2026-67404Critical
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)
Pearcleaner is a free, source-available and fair-code licensed mac app cleaner. The PearcleanerHelper is a privileged helper tool bundled with the Pearcleaner application. It is registered and activated only after the user approves a system prompt to allow privileged operations. Upon approval, the helper is configured as a LaunchDaemon and runs with root privileges. In versions 4.4.0 through 4.5.1, the helper registers an XPC service (com.alienator88.Pearcleaner.PearcleanerHelper) and accepts unauthenticated connections from any local process. It exposes a method that executes arbitrary shell commands. This allows any local unprivileged user to escalate privileges to root once the helper is approved and active. This issue is fixed in version 4.5.2.
