CVE-2025-51726
HighSummary
Instalator CyberGhostVPNSetup.exe (Windows) jest podpisany przy użyciu słabego algorytmu skrótu kryptograficznego SHA-1, co czyni go podatnym na ataki kolizyjne. Dodatkowo, instalator nie posiada wysokiej entropii w randomizacji układu adresów (ASLR), co zwiększa ryzyko udanych ataków na pamięć.
Risk Assessment
Organizacja jest narażona na ataki typu supply-chain oraz eskalację uprawnień poprzez fałszywe instalatory, co może prowadzić do nieautoryzowanego dostępu do systemów. Słabe zabezpieczenia mogą umożliwić atakującym łatwiejsze przeprowadzenie ataków na infrastrukturę IT.
Recommendation
Zaleca się aktualizację instalatora do wersji wykorzystującej silniejsze algorytmy kryptograficzne oraz wdrożenie polityk bezpieczeństwa, które wymuszają stosowanie ASLR. Należy również rozważyć wprowadzenie dodatkowych mechanizmów weryfikacji podpisów cyfrowych.

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.

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)
CyberGhostVPNSetup.exe (Windows installer) is signed using the weak cryptographic hash algorithm SHA-1, which is vulnerable to collision attacks. This allows a malicious actor to craft a fake installer with a forged SHA-1 certificate that may still be accepted by Windows signature verification mechanisms, particularly on systems without strict SmartScreen or trust policy enforcement. Additionally, the installer lacks High Entropy Address Space Layout Randomization (ASLR), as confirmed by BinSkim (BA2015 rule) and repeated WinDbg analysis. The binary consistently loads into predictable memory ranges, increasing the success rate of memory corruption exploits. These two misconfigurations, when combined, significantly lower the bar for successful supply-chain style attacks or privilege escalation through fake installers.
