——1Sudo through 1.9.17p2 fails to apply intercept policy checks to the execveat system call in ptrace-based intercept mode. Users permitted to run specific commands can execute denied programs by calling execveat directly or through fexecve, bypassing policy enforcement and logging.1d CVE-2026-6876—

——9ServiceNow has remediated a sandbox escape security issue that was identified in the Now Platform. This security issue could allow an unauthenticated user to execute arbitrary code within the Now Platform, potentially leading to more access to the Now Platform than intended. ServiceNow deployed a security update to hosted instances and ServiceNow provided the update to our partners and self-hosted customers. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.2d CVE-2026-592773.7 BAJ

——7Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.7, a project administrator can read files outside their repository through the App store metadata download feature, which resolves attacker-influenced paths without adequately confining them to the repository. This is an incomplete fix for CVE-2026-34242, whose original patch failed to fully prevent the path traversal, allowing the arbitrary file read to persist. A user with project-administrator privileges can therefore disclose the contents of files on the Weblate host that lie outside the project's repository. This issue is fixed in version 2026.7.2d CVE-2026-801987.5 ALT

——8Kimai versions before 2.56.0 fail to restrict the config() Twig function in sandboxed invoice and export templates, allowing administrators to access arbitrary configuration keys. Attackers with admin privileges can upload malicious templates to exfiltrate server-wide secrets including LDAP bind passwords and SAML private keys into invoice or export documents accessible to lower-privileged users.2d
