Descrição técnica

In the Eclipse Adoptium website (adoptium.net), in every deployment built from commit 0b24ea1 (2025-06-18) up to the fix in commit cbb53cf (2026-09-24), the post-download page /[locale]/download takes a download URL from the "link" query parameter and automatically navigates to it with a meta http-equiv="refresh". The URL is checked against a list of trusted prefixes using String.startsWith() on the raw string, while the browser applies RFC 3986 dot-segment normalisation before navigating, so a value such as https://github.com/adoptium/temurin/../../attacker/malware/releases/download/v1/jdk.exe passes the check but resolves to an attacker-controlled repository. A victim who follows a crafted adoptium.net link is shown the genuine "Thank you for downloading Eclipse Temurin" page while their browser downloads a binary of the attacker's choosing

———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to perform an account takeover due to an open redirect vulnerability. The redirect address used during sign-in is not sufficiently validated, which could allow authentication results to be sent to an attacker-controlled location.5h CVE-2026-172918.7 ALT

———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to perform account takeover due to an open redirect vulnerability. The redirect address used during OAuth 2.0 sign-in is not sufficiently validated, which could allow authentication results to be sent to an attacker-controlled location.5h CVE-2026-860449.6 CRÍ

———JupyterLab Desktop is the cross-platform desktop application for JupyterLab. Prior to 4.6.2-1, JupyterLab Desktop exposed getServerInfo to the renderer without confirming that the current page still had the local Jupyter server origin. In a local managed session using JupyterLab before 4.4.8, an attacker can place a crafted MathJax link in an untrusted notebook. If a victim opens the notebook and clicks the link, the existing renderer navigates to an attacker-controlled site while retaining access to the preload bridge. The site can call getServerInfo to obtain the local server URL and authentication token, then use the Jupyter REST API to create and trust a notebook that executes arbitrary code as the victim. Users whose environment already uses JupyterLab 4.4.8 or later are unaffected because the corrected link handling breaks the first step of the chain. This vulnerability is fixed in 4.6.2-1.13h CVE-2026-1046577.5 ALT

——0Missing integrity verification in the Progress Software Fiddler Download and Setup Skill on Linux, macOS, and Windows which allows an attacker to compromise or influence a release component and execute attacker-controlled code when a user runs the skill. On macOS, the skill stages the package at a predictable path and installs it with administrator privileges, which may allow code execution with root privileges after user approval. A local process may also replace the staged macOS package while the skill waits for approval.14h CVE-2026-351074.7 MÉD

——0HCL AION is affected by an open redirect vulnerability in the user menu of the GenAI web interface (UserMenu component). The redirect to the login page on logout used a URL taken from build configuration (NEXT_PUBLIC_LOGIN_URL) without validating the redirect destination. This may be used in phishing attacks, potentially resulting in unintended behavior or security impact under certain conditions.13h CVE-2026-351064.7 MÉD

——0HCL AION is affected by an open redirect vulnerability in the session-handling logic of the GenAI web interface (UserContext component, line 89). A second redirect to the login page in this component used a URL taken from build configuration (NEXT_PUBLIC_LOGIN_URL) without validating the redirect destination. This may be used in phishing attacks, potentially resulting in unintended behavior or security impact under certain conditions.13h
