CVE-2025-57800Audiobookshelf is an open-source self-hosted audiobook server. In versions 2.6.0 through 2.26.3, the application does not properly restrict redirect callback URLs during OIDC authentication. An attacker can craft a login link that causes Audiobookshelf to store an arbitrary callback in a cookie, which is later used to redirect the user after authentication. The server then issues a 302 redirect to the attacker-controlled URL, appending sensitive OIDC tokens as query parameters. This allows an attacker to obtain the victim's tokens and perform full account takeover, including creating persistent admin users if the victim is an administrator. Tokens are further leaked via browser history, Referer headers, and server logs. This vulnerability impacts all Audiobookshelf deployments using OIDC; no IdP misconfiguration is required. The issue is fixed in version 2.28.0. No known workarounds exist.
CVE-2017-16731An Unprotected Transport of Credentials issue was discovered in ABB Ellipse 8.3 through Ellipse 8.9 released prior to December 2017 (including Ellipse Select). A vulnerability exists in the authentication of Ellipse to LDAP/AD using the LDAP protocol. An attacker could exploit the vulnerability by sniffing local network traffic, allowing the discovery of authentication credentials.
CVE-2025-64308The Brightpick Mission Control web application exposes hardcoded credentials in its client-side JavaScript bundle.
CVE-2025-64309Brightpick Mission Control
discloses device telemetry, configuration, and credential information
via WebSocket traffic to unauthenticated users when they connect to a
specific URL. The unauthenticated URL can be discovered through basic
network scanning techniques.
CVE-2024-1509Brocade ASCG before 3.2.0 Web Interface is not
enforcing HSTS, as defined by RFC 6797. HSTS is an optional response
header that can be configured on the server to instruct the browser to
only communicate via HTTPS. The lack of HSTS allows downgrade attacks,
SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking
protections.
CVE-2025-61121Mobile Scanner Android App version 2.12.38 (package name com.glority.everlens), developed by Glority Global Group Ltd., contains a credential leakage vulnerability. Improper handling of cloud service credentials may allow attackers to obtain them and carry out unauthorized actions, such as sensitive information disclosure and abuse of cloud resources. Successful exploitation could result in privacy breaches and misuse of the platform infrastructure.

CVE-2021-38460A path traversal vulnerability in the Moxa MXview Network Management software Versions 3.x to 3.2.2 may allow an attacker to create or overwrite critical files used to execute code, such as programs or libraries.
CVE-2024-20395A vulnerability in the media retrieval functionality of Cisco Webex App could allow an unauthenticated, adjacent attacker to gain access to sensitive session information.
This vulnerability is due to insecure transmission of requests to backend services when the app accesses embedded media, such as images. An attacker could exploit this vulnerability by sending a message with embedded media that is stored on a messaging server to a targeted user. If the attacker can observe transmitted traffic in a privileged network position, a successful exploit could allow the attacker to capture session token information from insecurely transmitted requests and possibly reuse the captured session information to take further actions as the targeted user.
