Description

Vikunja before 2.7.1 contains an uncontrolled resource consumption vulnerability that allows authenticated users to exhaust server memory by requesting avatars at many distinct sizes. Attackers can upload a noisy avatar and fetch it at each size up to 1024, caching roughly a gigabyte per account without eviction and causing the API process to be OOM-killed.

CVE-2026-119156

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpdm_reg[first_name], wpdm_reg[last_name], wpdm_reg[user_login]' parameter in all versions up to, and including, 7.5.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the site to have "Anyone can register" enabled, the plugin's [wpdm_reg_form] shortcode published on a public page, and at least one package authored by user ID 1 rendered with the Spotlight link template.

CVE-2026-99277

In the Linux kernel, the following vulnerability has been resolved: ksmbd: hold a connection reference for each session channel ksmbd_session_unregister() removes a session from the global and per- connection tables before dropping the table reference. A concurrent reference holder can keep the session and its channel list alive after those removals. Connection cleanup can no longer find the unpublished session to remove its channels. Since a channel only stores a raw conn pointer, the connection can be freed while another session reference holder is still accessing it, for example during SMB3.1.1 binding or a procfs read. Take a connection reference when registering a channel and release it on insertion failure, channel removal, or final session destruction. Keep the channels and signing keys until the session is destroyed so a response can still be signed after the session has been unregistered.

CVE-2026-123501

Vikunja before 2.7.1 contains an uncontrolled resource consumption vulnerability that allows authenticated users to exhaust server memory through concurrent image decodes in avatar and background uploads. Attackers can send several parallel tiny, highly compressible PNGs decoded at up to 50 megapixels each, pushing the API process into memory pressure or an OOM kill.
