CVE-2026-20709 (GCVE-0-2026-20709)
Vulnerability from cvelistv5 – Published: 2026-04-08 18:20 – Updated: 2026-04-08 19:50

Summary
Use of Default Cryptographic Key in the hardware for some Intel(R) Pentium(R) Processor Silver Series, Intel(R) Celeron(R) Processor J Series, Intel(R) Celeron(R) Processor N Series may allow an escalation of privilege. Hardware reverse engineer adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via physical access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.

Title
rachelos WeRSS we-mp-rss JWT auth.py default key
Summary
A vulnerability was detected in rachelos WeRSS we-mp-rss up to 1.4.8. This issue affects some unknown processing of the file core/auth.py of the component JWT Handler. Performing a manipulation of the argument SECRET_KEY results in use of default cryptographic key. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitability is assessed as difficult. The exploit is now public and may be used.

CVE-2026-25815 (GCVE-0-2026-25815)
Vulnerability from cvelistv5 – Published: 2026-02-05 21:14 – Updated: 2026-02-09 19:31 Disputed
VLAI
Summary
Fortinet FortiOS through 7.6.6 allows attackers to decrypt LDAP credentials stored in device configuration files, as exploited in the wild from 2025-12-16 through 2026 (by default, the encryption key is the same across all customers' installations). NOTE: the Supplier's position is that the instance of CWE-1394 is not a vulnerability because customers "are supposed to enable" a non-default option that eliminates the weakness. However, that non-default option can disrupt functionality as shown in the "Managing FortiGates with private data encryption" document, and is therefore intentionally not a default option.

NOTE: the Supplier\u0027s position is that the instance of CWE-1394 is not a vulnerability because customers \"are supposed to enable\" a non-default option that eliminates the weakness. However, that non-default option can disrupt functionality as shown in the \"Managing FortiGates with private data encryption\" document, and is therefore intentionally not a default option."

CVE-2026-5039 (GCVE-0-2026-5039)
Vulnerability from cvelistv5 – Published: 2026-04-23 16:10 – Updated: 2026-04-28 17:45

Title
Predictable Default Cryptographic Key Used for DES Encryption in TP-Link TL-WL841N
Summary
TP-Link TL-WR841N v13 uses DES-CBC encryption in the TDDPv2 debug protocol with a cryptographic key derived from default web management credentials, making the key predictable if device is left in default configuration. A network-adjacent attacker can exploit this weakness to gain unauthorized access to the protocol, read debug data, modify certain device configuration values, and trigger device reboot, resulting in loss of integrity and a denial-of-service condition.
