Description

This security bulletin contains information about 5 vulnerabilities.


1) Improper Encoding or Escaping of Output (CVE-ID: CVE-2026-34483)

CWE-ID: CWE-116 - Improper Encoding or Escaping of Output

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to inject arbitrary JSON into the JSON access log.

The vulnerability exists due to incomplete escaping in the JSON access log when handling requests with non-default Connector attributes relaxedPathChars and/or relaxedQueryChars. A remote attacker can send a specially crafted request to inject arbitrary JSON into the JSON access log.

Only configurations using non-default values for relaxedPathChars and/or relaxedQueryChars are affected.


2) Protection Mechanism Failure (CVE-ID: CVE-2026-34486)

CWE-ID: CWE-693 - Protection Mechanism Failure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass the EncryptInterceptor.

The vulnerability exists due to an implementation error in the EncryptInterceptor when processing traffic protected by the fix for #VU125739 (CVE-2026-29146). A remote attacker can exploit the flawed handling to bypass the EncryptInterceptor.


3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2026-29146)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to decrypt protected communications.

The vulnerability exists due to the use of a padding-oracle-prone cryptographic mode in EncryptInterceptor when processing encrypted traffic with the default CBC configuration. A remote attacker can perform a padding oracle attack to decrypt protected communications.


4) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2026-34487)

CWE-ID: CWE-532 - Information Exposure Through Log Files

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to insertion of sensitive information into log output in the cloud membership for clustering component when writing log messages. A remote attacker can trigger log entries that expose the Kubernetes bearer token to disclose sensitive information.


5) Improper Certificate Validation (CVE-ID: CVE-2026-34500)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to bypass client certificate authentication.

The vulnerability exists due to improper certificate validation in CLIENT_CERT authentication when processing OCSP checks with FFM and soft-fail disabled. A remote user can present a certificate in affected scenarios to bypass client certificate authentication.

Only some scenarios using FFM are affected.
