CVE-2026-1146596.5 MED—
———Grav Flex Objects plugin 1.4.0 before 1.4.17 contains an authorization bypass because its generic /api/v1/flex-objects/pages API routes check only directory-level admin.pages permissions, without enforcing the Pages API's api.pages.read/write permissions or page-level permissions rules. Authenticated non-super users with api.access and admin.pages or admin.configuration.pages permissions can read page source and frontmatter, modify content, or delete pages they are denied.17hCVE-2026-1108657.1 HIG7.7%
——2Renovate before 44.60.1 contains an allowlist bypass vulnerability that allows repository users to evade the allowedHeaders restriction by placing hostRules headers inside shared presets. Attackers can supply internal or externally sourced presets with unvalidated hostRules[].headers to inject custom HTTP headers into requests Renovate sends to other hosts.6dCVE-2026-699795.5 MED26.8%
——8Improper protection of alternate path in Windows AppX Deployment Service allows an authorized attacker to bypass a security feature locally.6dCVE-2026-1073527.7 HIG9.4%
——3Missing authorization checks in Amazon Athena engine version 3 request handling could have allowed an authenticated user to read limited query metadata (AWS account identifiers and SQL statement text) from other AWS accounts. Query results, credentials, and Amazon S3 data were not affected. AWS remediated the issue on September 1, 2026, and has confirmed no customer metadata was accessed. No customer action is required.11dCVE-2026-890396.5 MED30.6%
——9A caller who can invoke the convert_playwright_script prompt in mcp-k6 can pass a bare file path as the playwright_script argument and receive the contents of any file readable by the user running the server, including SSH keys and cloud credentials in that user's home directory (path traversal). The working-directory restriction applied to '@'-prefixed paths can also be bypassed with a symbolic link inside the working directory that points outside it.16dCVE-2026-933535.3 MED18.7%
——6copyparty contains a volume restriction bypass vulnerability in its SFTP front end that allows authenticated SFTP users to create, remove, and truncate arbitrary paths outside permitted volume boundaries by exploiting three handlers that bypass the xvol volflag enforcement. The _mkdir, _rmdir, and _chattr handlers construct destination paths using vfs.get(), vn.canonical(), and os.path.join() without invoking the chk_ap access check, enabling attackers to traverse symlinks leaving a volume's top directory and perform unauthorized file creation, deletion, or truncation via SSH_FXP_SETSTAT operations on paths outside any volume the account is authorized to access.24d
