    The expat and elementtree parsers use insufficient entropy for XML hash-flooding protection

    `xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.

    pyLoad: Unauthenticated traceback disclosure via global exception handler in WebUI

    pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, pyload-ng WebUI returns full Python traceback details to clients on unhandled exceptions. Because /web/<path:filename> is reachable without authentication and renders attacker-controlled template names, an unauthenticated user can reliably trigger a server exception (for example by requesting a non-existent template) and receive internal stack traces in the HTTP response. This vulnerability is fixed in 0.5.0b3.dev100.

    pyLoad: Path Traversal via Package Folder Name in set_package_data

    pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, when passing a folder name in the set_package_data() API function call inside the data object with key "_folder", there is no sanitization at all, allowing a user with Perms.MODIFY to specify arbitrary directories as download locations for a package. This vulnerability is fixed in 0.5.0b3.dev100.

    pyLoad: Path Traversal via Package Folder Name

    pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, package folder names are sanitized using insufficient string replacement. The pattern ....// becomes .._ after replacement (partial removal), leaving .. which can be exploited when the path is later resolved by the OS. This vulnerability is fixed in 0.5.0b3.dev100.

    pyload-ng: non-admin SETTINGS users can disable outbound TLS peer verification

    pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, the set_config_value() API method (@permission(Perms.SETTINGS)) in src/pyload/core/api/__init__.py gates security-sensitive options behind a hand-maintained allowlist ADMIN_ONLY_CORE_OPTIONS. The option ("general", "ssl_verify") is not on that allowlist. Any authenticated user with the non-admin SETTINGS permission can set general.ssl_verify = off, and every subsequent outbound pycurl request is made with SSL_VERIFYPEER=0 and SSL_VERIFYHOST=0 — TLS peer and hostname verification are fully disabled. An on-path attacker can then present forged certific

    Server-Side Request Forgery (SSRF) in mlflow/mlflow

    A Server-Side Request Forgery (SSRF) vulnerability exists in MLflow versions prior to 3.9.0. The `_create_webhook()` function in `mlflow/server/handlers.py` accepts a user-controlled `url` parameter without validation, and the `_send_webhook_request()` function in `mlflow/webhooks/delivery.py` sends HTTP POST requests to this attacker-controlled URL. This allows an authenticated attacker to force the MLflow backend to send HTTP requests to internal services, cloud metadata endpoints, or arbitrary external servers. The lack of input sanitization, URL scheme filtering, or allowlist validation on the webhook URL enables exploitation, potentially

    oxidize-pdf: NaN/inf bypass in colour content-stream emission causes PDF rejection (DoS)

    ### Impact `oxidize-pdf` defines `Color` as a `pub enum` with public tuple-struct variants `Rgb(f64, f64, f64)`, `Gray(f64)`, and `Cmyk(f64, f64, f64, f64)`. The constructors `Color::rgb`, `Color::gray`, and `Color::cmyk` clamp incoming components to `[0.0, 1.0]`, but because the variants are `pub`, callers can construct values directly without going through the constructors: ```rust let safe = Color::rgb(f64::NAN, 0.5, 0.5); // clamps NaN to 0.0 let attack = Color::Rgb(f64::NAN, 0.5, 0.5); // bypasses clamp Color: Copy allows the non-finite value to propagate freely through API surfaces and serialisation.

A user with access to the API could see the filename and name of documents and images in private collections. This vulnerability is fixed in 7.0.7, 7.3.2, and 7.4.

    Wagtail: Improper permission handling when copying pages

    Wagtail is an open source content management system built on Django. Prior to 7.0.7, 7.3.2, and 7.4, a CMS user with limited access to pages could copy a page they don't have access to to an area of the site they do. Once coped, they'd be able to view its contents, and potentially publish it. Permissions were correctly checked for the copy destination, but not for the source page. This vulnerability is fixed in 7.0.7, 7.3.2, and 7.4.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. This vulnerability is fixed in 7.0.7, 7.3.2, and 7.4.

    pgAdmin 4: Account-lockout bypass via Flask-Security default /login view

    Improper restriction of excessive authentication attempts (CWE-307) in pgAdmin 4. pgAdmin enforces MAX_LOGIN_ATTEMPTS only inside its custom /authenticate/login view. Flask-Security's default /login view, which is registered automatically by security.init_app() and is reachable on every server, never consulted the User.locked field: pgAdmin's User model relied on Flask-Security's UserMixin.is_locked() (which always returns 'not locked') and Flask-Login's is_active (which only checks the active column, not locked). An attacker who triggered an account lockout via /authenticate/login could therefore obtain a session by re-submitting valid cred

    pgAdmin 4: Symbolic-link path traversal in File Manager allows arbitrary file write

    Symbolic-link path traversal (CWE-61, CWE-22) in pgAdmin 4 File Manager. check_access_permission used os.path.abspath, which resolves '..' but does not resolve symbolic links, while the subsequent kernel write follows symlinks. An authenticated user could plant a symbolic link inside their own storage directory pointing outside it and induce pgAdmin to write to any path reachable by the pgAdmin process. Fix switches the access check to os.path.realpath for both source and destination, and adds an _open_upload_target helper that opens the target with O_NOFOLLOW (mode 0o600) to close the leaf-component TOCTOU between the access check and the

    pgAdmin 4: Unsafe deserialization (CWE-502) in file-backed session manager leads to remote code execution

    Deserialization of untrusted data (CWE-502) in pgAdmin 4 FileBackedSessionManager. The session manager performed unsafe deserialization of session-file contents (using Python's standard object-serialization module) before performing any HMAC integrity check. Any file dropped into the sessions directory was deserialized unconditionally. An authenticated user with write access to the sessions directory (whether by misconfiguration or in combination with another path-traversal flaw) could plant a crafted serialized payload to achieve operating-system level remote code execution under the pgAdmin process identity.
