CWE-212

Wasmtime is a standalone runtime for WebAssembly. Prior to version 2.0.2, there is a bug in Wasmtime’s implementation of its pooling instance allocator where when a linear memory is reused for another instance the initial heap snapshot of the prior instance can be visible, erroneously to the next instance. This bug has been patched and users should upgrade to Wasmtime 2.0.2. Other mitigations include disabling the pooling allocator and disabling the `memory-init-cow`.

An authenticated user with access to the Strapi admin panel can view private and sensitive data, such as email and password reset tokens, for API users if content types accessible to the authenticated user contain relationships to API users (from:users-permissions). There are many scenarios in which such details from API users can leak in the JSON response within the admin panel, either through a direct or indirect relationship. Access to this information enables a user to compromise these users’ accounts if the password reset API endpoints have been enabled. In a worst-case scenario, a low-privileged user could get access to a high-privileged API account, and could read and modify any data as well as block access to both the admin panel and API by revoking privileges for all other users.

An authenticated user with access to the Strapi admin panel can view private and sensitive data, such as email and password reset tokens, for other admin panel users that have a relationship (e.g., created by, updated by) with content accessible to the authenticated user. For example, a low-privileged “author” role account can view these details in the JSON response for an “editor” or “super admin” that has updated one of the author’s blog posts. There are also many other scenarios where such details from other users can leak in the JSON response, either through a direct or indirect relationship. Access to this information enables a user to compromise other users’ accounts by successfully invoking the password reset workflow. In a worst-case scenario, a low-privileged user could get access to a “super admin” account with full control over the Strapi instance, and could read and modify any data as well as block access to both the admin panel and API by revoking privileges for all other users.

Internet Routing Registry daemon version 4 is an IRR database server, processing IRR objects in the RPSL format. IRRd did not always filter password hashes in query responses relating to `mntner` objects and database exports. This may have allowed adversaries to retrieve some of these hashes, perform a brute-force search for the clear-text passphrase, and use these to make unauthorised changes to affected IRR objects. This issue only affected instances that process password hashes, which means it is limited to IRRd instances that serve authoritative databases. IRRd instances operating solely as mirrors of other IRR databases are not affected. This has been fixed in IRRd 4.2.3 and the main branch. Versions in the 4.1.x series never were affected. Users of the 4.2.x series are strongly recommended to upgrade. There are no known workarounds for this issue.

Wire webapp is a web client for the wire messaging protocol. In versions prior to 2022-01-27-production.0 expired ephemeral messages were not reliably removed from local chat history of Wire Webapp. In versions before 2022-01-27-production.0 ephemeral messages and assets might still be accessible through the local search functionality. Any attempt to view one of these message in the chat view will then trigger the deletion. This issue only affects locally stored messages. On premise instances of wire-webapp need to be updated to 2022-01-27-production.0, so that their users are no longer affected. There are no known workarounds for this issue.
