  1. Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 19.3-19.30 and 21.3-21.21. Easily exploitable vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Java VM. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java VM accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).•CVE-2026-35229
  2. Vulnerability in the Oracle Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Event Management). Supported versions that are affected are 13.5 and 24.1. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle Enterprise Manager Base Platform. While the vulnerability is in Oracle Enterprise Manager Base Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).•CVE-2026-34279
  3. DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a JDBC parameter blocklist bypass vulnerability in the MySQL datasource configuration. The Mysql class uses Lombok's @Data annotation, which auto-generates a public setter for the illegalParameters field that contains the JDBC security blocklist. When a datasource configuration is submitted as JSON, Jackson deserialization calls setIllegalParameters with an attacker-supplied empty list, replacing the blocklist before getJdbc() validation runs. This allows an authenticated attacker to include dangerous JDBC parameters such as allowLoadLocalInfile=true, and by pointing the datasource at a rogue MySQL server, exploit the LOAD DATA LOCAL INFILE protocol feature to read arbitrary files from the DataEase server filesystem, including sensitive environment variables and database credentials. This issue has been fixed in version 2.10.21.•CVE-2026-40899
  4. A critical vulnerability in the Talend JobServer and Talend Runtime allows unauthenticated remote code execution via the JMX monitoring port. The attack vector is the JMX monitoring port of the Talend JobServer. The vulnerability can be mitigated for the Talend JobServer by requiring TLS client authentication for the monitoring port; however, the patch must be applied for full mitigation. For Talend ESB Runtime, the vulnerability can be mitigated by disabling the JobServer JMX monitoring port, which is disabled by default from the R2024-07-RT patch.•CVE-2026-6264
  5. A vulnerability was identified in uclouvain openjpeg up to 2.5.4. This impacts the function opj_pi_initialise_encode in the library src/lib/openjp2/pi.c. The manipulation leads to integer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is 839936aa33eb8899bbbd80fda02796bb65068951. It is suggested to install a patch to address this issue.•CVE-2026-6192
