Vulnerabilities

CVE-2026-77089 is an authentication bypass flaw (CWE-290, authentication bypass by alternate path or channel) in the Command Center API, affecting how privileges are managed. Per the CVSS 4.0 vector, it is remotely exploitable over the network (AV:N) with low attack complexity and no prior privileges or user interaction required (PR:N/UI:N), so a single unauthenticated request to the API can trigger it. A successful attacker gains unauthorized access to privileged functionality, and the critical 9.3 rating with high confidentiality, integrity, and availability impacts indicates this could escalate to broad unauthorized control of the affected system. Affected users are customers running the affected Command Center software; the advisory directs all customers to upgrade to the resolved maintenance release but does not name the vendor or publish specific version ranges. Exploitation status: no public proof-of-concept is known, the flaw is not in CISA KEV, and EPSS assigns a 0.3% probability of exploitation within 30 days (percentile 26), indicating no known exploitation so far.

Do: Upgrade Command Center to the maintenance release issued by the vendor; consult the vendor's advisory for the exact fixed version, since no version numbers were specified in this data. Until patched, restrict network exposure of the Command Center API (firewall/ACL rules or segmentation) because the flaw is exploitable remotely without credentials or user interaction. Review API and audit logs for unauthenticated requests performing privileged operations, which would indicate possible prior exploitation.

CommServe contained an authorization bypass vulnerability affecting a limited set of command execution operations. Software customers upgrade to resolved maintenance release. Update all Commvault installations, including Commserve, Webserver, Command Center, Media Agents, Clients and HyperScale X.

OpenLearn is open-source educational forum software. Prior to commit 844b2a40a69d0c4911580fe501923f0b391313ab, when `safeMode` is enabled, unapproved forum posts are hidden from the public list, but the direct post-read procedure still returns the full post to anyone with the post UUID. Commit 844b2a40a69d0c4911580fe501923f0b391313ab fixes the issue.

WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause information disclosure or denial-of-service via a special crafted packet. The leaked memory could be used to bypass ASLR and facilitate further exploitation.

The Report Builder component of the application stores user input directly in a web page and displays it to other users, which raised concerns about a possible Cross-Site Scripting (XSS) attack. Proper management of this functionality helps ensure a secure and seamless user experience. Although the user input is not validated in the report creation, these scripts are not executed when the report is run by end users. The script is executed when the report is modified through the report builder by a user with edit permissions. The Report Builder is part of the WebConsole. The WebConsole package is currently end of life, and is no longer maintained. We strongly recommend against installing or using it in any production environment. However, if you choose to install it, for example, to access functionality like the Report Builder, it must be deployed within a fully isolated network that has no access to sensitive data or internet connectivity. This is a critical security precaution, as the retired package may contain unpatched vulnerabilities and is no longer supported with updates or fixes.

A vulnerability in TeamViewer DEX Client (former 1E client) - Content Distribution Service (NomadBranch.exe) prior version 25.11 for Windows allows malicious actors to bypass file integrity validation via a crafted request. By providing a valid hash for a malicious file, an attacker can cause the service to incorrectly validate and process the file as trusted, enabling arbitrary code execution under the Nomad Branch service context.

A security vulnerability has been identified that allows remote attackers to perform unauthorized file system access through a path traversal issue. The vulnerability may lead to remote code execution.

CVE-2025-3928 is an unspecified vulnerability in the Commvault Web Server, the web administration component of Commvault's data protection platform, which can be exploited over the network by a remote attacker who holds valid (low-privilege) authenticated access. According to the Commvault advisory, attackers use the flaw to create and execute webshells on the web server, and the CVSS 4.0 score of 8.7 (High) reflects high impact to the confidentiality, integrity, and availability of the vulnerable web server component. It affects Commvault Web Server on both Windows and Linux across the supported release streams, with fixes delivered in 11.36.46, 11.32.89, 11.28.141, and 11.20.217. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2025-04-28, and Commvault has confirmed that hackers exploited it in the wild as a zero-day, with related reporting noting heightened Silk Typhoon (Chinese nation-state) attack activity. No public proof-of-concept is known, but the confirmed real-world zero-day exploitation makes patching urgent.

Do: Upgrade the Commvault Web Server to 11.36.46, 11.32.89, 11.28.141, or 11.20.217, matching your current release stream, on both Windows and Linux platforms. Because the flaw was exploited as a zero-day, hunt for attacker-created webshells and unexpected accounts, scripts, or scheduled tasks on Commvault web server hosts, review authentication logs for suspicious logins, and restrict the Commvault web interface to trusted networks. Federal agencies must apply vendor mitigations per CISA instructions or follow BOD 22-01 guidance for cloud services, or discontinue use if mitigations are unavailable.

Commvault Command Center (Innovation Release 11.38.0 through 11.38.20) is vulnerable to a path traversal flaw (CWE-22) that requires no authentication (CWE-306). An unauthenticated remote attacker uploads a maliciously crafted ZIP file masquerading as an install package to the Command Center web interface; when the target server expands the archive, path traversal lets attacker-controlled files, including malicious JSP webshells, be written outside the intended location. The result is unauthenticated remote code execution on the backup management server, giving attackers a foothold in a core enterprise data-protection component. Any organization running the affected 11.38 release train of Command Center is exposed, particularly if the console is reachable from the internet. The flaw is being actively exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2025-05-02, carries a 97.7% EPSS exploitation probability, and public PoC exploit code is available.

Do: Upgrade Command Center to 11.38.20 with hotfixes SP38-CU20-433 and SP38-CU20-436, or to 11.38.25 with SP38-CU25-434 and SP38-CU25-438. Until patched, restrict internet exposure of the Command Center web console and check for signs of compromise such as unexpected JSP files or webshells written by the application. Federal agencies must apply vendor mitigations per CISA BOD 22-01 guidance or discontinue use of the product.

The Click Mag - Viral WordPress News Magazine/Blog Theme theme for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the propanel_of_ajax_callback() function in all versions up to, and including, 3.6.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users.

The ZoxPress - The All-In-One WordPress News Theme theme for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the 'backup_options' and 'restore_options' functions in all versions up to, and including, 2.12.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
