Descrição técnica

Rembg is a tool to remove images background. Prior to 2.0.82, the public /api/remove endpoint passes attacker-controlled extras.sam_model through rembg/commands/s_command.py to rembg/sessions/sam.py, where it is interpolated into SAM filenames and GitHub download URLs passed to pooch.retrieve() without a pinned hash. An unauthenticated attacker can supply a sam_model value combining path traversal with URL fragment syntax to exploit the HTTP request discarding the fragment while the local POSIX path retains it. The first request primes the attacker-selected path tree, and an identical repeated request downloads malicious ONNX encoder and decoder files beside a readable target file. The graphs can load the target through ONNX external data and encode its bytes into the returned PNG mask, disclosing complete files accessible to the rembg process and allowing arbitrary ONNX computation. This issue is fixed in version 2.0.82.

—

———OpenEMR before 8.4.0 contains a local file inclusion in the ESign router (library/ESign/Router.php), which passes the unsanitized module parameter into a require_once of '<module>/Controller.php', and the fax module's faxProcessUploads writes attacker-named files to a predictable temp path without extension checks. Authenticated attackers can upload a PHP file named Controller.php, then request interface/esign/index.php with a traversing module parameter to include it and execute arbitrary code.1h CVE-2026-1244577.6 ALT

—

———OpenEMR before 8.3.0 contains a path traversal vulnerability in interface/billing/sl_eob_process.php that allows authenticated users to write and read files by supplying unsanitized eraname values. Attackers without billing privileges can inject ../ sequences to create ERA report .html files anywhere the web user can write and parse arbitrary .edi files echoed into the report.1h CVE-2026-1244286.5 MÉD

—

———Craft CMS from 5.7.0 before 5.11.2 contains an arbitrary file read vulnerability that allows authenticated control panel users to read SVG files by posting arbitrary paths to the app/icon-svg endpoint. Attackers can supply aliases or absolute paths, which are resolved without permission checks, to read any SVG-content file readable by the PHP process, including files outside the Craft installation.1h CVE-2026-1244247.1 ALT

—

———WWBN AVideo contains a path traversal vulnerability in plugin/AI/receiveAsync.json.php that allows holders of any valid AI token to write arbitrary .vtt files by injecting traversal sequences into the unsanitized response[lang] parameter. Attackers can send a type=translation request with a crafted lang value to plant attacker-controlled content in the webroot or overwrite other users' subtitle files.1h CVE-2026-1243305.0 MÉD

———A vulnerability was determined in FlowCI flow-core-x up to 1.23.49. This affects the function exist/save/read/remove of the file store/src/main/java/com/flowci/store/LocalFileManager.java of the component LocalFileManager. This manipulation of the argument fileName causes path traversal. It is possible to initiate the attack remotely. A high degree of complexity is needed for the attack. The exploitability is reported as difficult. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.2h CVE-2026-1243295.0 MÉD
