CVE-2022-4939
CriticalSummary
Wtyczka WCFM Membership dla WordPressa jest podatna na eskalację uprawnień w wersjach do 2.10.0 włącznie, z powodu braku sprawdzenia uprawnień w akcji AJAX wp_ajax_nopriv_wcfm_ajax_controller, która kontroluje ustawienia członkostwa. Umożliwia to nieautoryzowanym atakującym modyfikację formularza rejestracji członkostwa, co pozwala im ustawić rolę rejestracji na dowolnego użytkownika, w tym administratora.
Risk Assessment
Atakujący mogą zarejestrować się jako administrator, co stwarza poważne zagrożenie dla bezpieczeństwa systemu i danych użytkowników. Taka eskalacja uprawnień może prowadzić do pełnej kontroli nad witryną.
Recommendation
Zaleca się aktualizację wtyczki WCFM Membership do najnowszej wersji, aby usunąć tę podatność. Dodatkowo warto przeprowadzić audyt uprawnień użytkowników oraz monitorować rejestracje w systemie.

The Prime Mover – Backup and Migration plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.2.1 via deserialization of untrusted input in the migration search-and-replace routine. An unauthenticated attacker can store a crafted, base64-encoded serialized object in wp_comments.comment_content through the standard comment-submission endpoint. When an administrator performs a routine export or restore, the plugin base64-decodes that stored value and passes it to unserialize() with no allowed_classes restriction. A Property-Oriented Programming (POP) chain is present in the plugin's own bundled Freemius library, so no additional plugin or theme is required.
- CVE-2026-115931Critical
Postiz lets a signed-in user ask the backend to run a function on one of their connected channels, but the backend did not restrict which functions could be requested, allowing calls to internal helpers. One helper reads a file from the server's disk (e.g., environment file with the session signing secret, database address, and service credentials), and another makes the backend process exit with a single request. Self-registration is open by default, so no existing account or action by another user is needed.

Wasmtime prior to 36.0.19, 48.0.7, and 49.0.4 has a flaw in the Cranelift compiler on aarch64. A br_table instruction with more than ~256,000 targets can be miscompiled, allowing a jump to arbitrary code and sandbox escape.
- CVE-2026-115889Critical
Wasmtime prior to 36.0.19 and 43.0.0 has a flaw in the Cranelift compiler where SSA value indices can silently overflow when compiling large Wasm functions. This can cause miscompilation, type confusion, and sandbox escape.
- CVE-2026-115812Critical
A relative path traversal during model archive extraction in AWS Multi Model Server 1.1.11 and earlier allows remote actors to execute arbitrary code via a crafted model archive. The project is end of life and no fixed version is available.
- CVE-2026-55486Critical
In Goobi viewer from version 25.08 to before 26.05, the IIIF Auth 2.0 endpoints auth/login and auth/token accept an origin query parameter without validation and embed it into the Content-Security-Policy header and an HTML response body as a postMessage argument. Since the attacker controls both calls, the unescaped value yields reflected XSS.
- CVE-2026-53942Critical
In conda/conda prior to commit 9c0f238, a GitHub Actions Pwn Request vulnerability remains in .github/workflows/update.yml. It is triggered by comments containing @conda-bot render or @conda-bot recreate, allowing an untrusted PR to reach Jinja2 template rendering in a privileged token context.
- CVE-2026-46652Critical
In Goobi viewer from version 24.03 to before 26.05, ExternalFilesDownloader.getFilename() extracts the filename from a server-supplied Content-Disposition header and passes it directly to Path.resolve() without stripping directory components. A malicious HTTP server can supply an absolute path or ../ sequences, writing attacker-controlled content to an arbitrary path, leading to remote code execution.
- CVE-2026-46651Critical
In Goobi viewer from version 24.03 to before 26.05, the DownloadTaskEndpoint WebSocket endpoint (/tasks/download/monitor.socket) in goobi-viewer-core accepts download requests from unauthenticated users. This issue has been patched in version 26.05.
- CVE-2026-53921Critical
In odhcpd (the DHCPv6/DHCPv4/RA server used by OpenWrt) prior to version 25.12, the DHCPv6 IA response handler writes past a fixed 512-byte stack buffer (pdbuf) when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two independent overflow sites exist in the same call chain, both reachable over the network via a single unauthenticated UDP packet. odhcpd runs as root on OpenWrt, and embedded targets often lack stack canaries and ASLR, making code execution realistic.
Original NVD description (English source)
THe WCFM Membership plugin for WordPress is vulnerable to privilege escalation in versions up to, and including 2.10.0, due to a missing capability check on the wp_ajax_nopriv_wcfm_ajax_controller AJAX action that controls membership settings. This makes it possible for unauthenticated attackers to modify the membership registration form in a way that allows them to set the role for registration to that of any user including administrators. Once configured, the attacker can then register as an administrator.
