CVE-2026-46400 - HAXCMS PHP has a File Upload Validation Bypass
CVE ID :CVE-2026-46400
Published : June 5, 2026, 8:17 p.m. | 3 hours, 7 minutes ago
Description :HAX CMS helps manage microsite universe with PHP or NodeJs backends. Starting in version 11.0.6 and prior to version 25.0.0, the file upload functionality in HAXCMS PHP only validates file extensions using a regex pattern without checking the actual file content or MIME type. This allows attackers to upload malicious files (e.g., PHP webshells) disguised as legitimate image files, potentially leading to remote code execution. Version 25.0.0 contains a fix for the issue.

CVE-2026-11423 - Path Traversal in Altium Enterprise Server Collaboration Service Allows Privilege Escalation
CVE ID :CVE-2026-11423
Published : June 5, 2026, 9:16 p.m. | 2 hours, 8 minutes ago
Description :A path traversal vulnerability exists in the Altium Enterprise Server Collaboration Service due to improper handling of user-supplied filenames in the MCAD and Simulation file download flows. A regular authenticated user can submit a collaboration message containing a crafted filename, which is later used to construct the download path on the server without validation, allowing arbitrary files to be read from the server filesystem. Because the readable files include the server's master configuration, which stores credentials for privileged accounts, exploitation can lead to authenticating as a system administrator and gaining full control of the server. Altium 365 cloud deployments are not affected.

CVE-2026-45409 - Internationalized Domain Names in Applications (IDNA): Specially crafted inputs to idna.encode() can bypass CVE-2024-3651 fix
CVE ID :CVE-2026-45409
Published : June 5, 2026, 10:06 p.m. | 1 hour, 19 minutes ago
Description :Internationalized Domain Names in Applications (IDNA) for Python provides support for Internationalized Domain Names in Applications (IDNA) and Unicode IDNA Compatibility Processing. In versions prior to 3.15, payloads such as `"\u0660" * N` or `"\u30fb" * N + "\u6f22"` utilize the `valid_contexto` function prior to length rejection, and for high values of `N` will take a long time to process. This is the same issue as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. A specially crafted argument to the `idna.encode()` function could consume significant resources. This may lead to a denial-of-service. Starting in version 3.14, the function rejects long inputs as soon as practicable prior to any further processing to minimize resource consumption. In version 3.15, this approach was extended to lesser used alternate functions (i.e. per-label conversions and codec support). A workaround is available. Domain names cannot exceed 253 characters in length. If this length limit is enforced prior to passing the domain to the `idna.encode()` function, it should no longer consume significant resources. This is triggered by arbitrarily large inputs that would not occur in normal usage, but may be passed to the library assuming there is no preliminary input validation by the higher-level application.

CVE-2026-11424 - Server-Side Request Forgery in Altium Platform Design GraphQL Service Allows Information Disclosure
CVE ID :CVE-2026-11424
Published : June 5, 2026, 10:16 p.m. | 1 hour, 8 minutes ago
Description :A server-side request forgery (SSRF) vulnerability exists in a GraphQL service component shared by Altium Enterprise Server and Altium 365. An authenticated user can submit a request whose input is treated as a URL by the server and used to issue an outbound HTTP GET request without URL validation or destination filtering. The response body is then returned to the user. This allows an authenticated attacker to reach internal services and metadata endpoints that would not otherwise be accessible from the public network, and to retrieve their contents. The impact is information disclosure and internal infrastructure reconnaissance; the request primitive is limited to HTTP GET with no custom headers. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.

CVE-2026-11429 - Path Traversal in Altium Git Service Allows Remote Code Execution
CVE ID :CVE-2026-11429
Published : June 5, 2026, 10:16 p.m. | 1 hour, 8 minutes ago
Description :A path traversal vulnerability exists in the Git Service component shared by Altium Enterprise Server and Altium 365. The service accepts a sequence of post-clone file-manipulation operations that use user-supplied paths without validation, allowing an authenticated user with basic git access to move arbitrary files outside the intended repository area. This file-move primitive can be used to place attacker-controlled script content into directories where it is later executed by the service, resulting in remote code execution under the Git Service account. On multi-tenant Altium 365 deployments, this could have allowed access to data belonging to other tenants on the same infrastructure node. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.

Description :A path traversal vulnerability exists in the Projects Service download endpoint shared by Altium Enterprise Server and Altium 365. An authenticated user can supply a crafted path parameter that bypasses validation, allowing arbitrary files (including entire directories returned as archives) to be read from the server filesystem. Because the readable files include service configuration and credential material, exploitation can be used to gather information enabling further compromise. The issue can be combined with CVE-2026-11424 to reach the cloud-side endpoint. On multi-tenant Altium 365 deployments, the readable configuration could have exposed credentials shared across services.

CVE-2026-7654 - Admin Columns <= 7.0.18 - Authenticated (Contributor+) PHP Object Injection to Remote Code Execution via Custom Field Meta Value
CVE ID :CVE-2026-7654
Published : June 5, 2026, 10:28 p.m. | 57 minutes ago
Description :The Admin Columns plugin for WordPress is vulnerable to PHP Object Injection leading to Remote Code Execution in versions up to and including 7.0.18. This is due to the use of `unserialize()` without an `allowed_classes` restriction in the `IdsToCollection::get_ids_from_string()` function, which processes attacker-controlled post meta values without proper validation. This makes it possible for authenticated attackers with Contributor-level access and above to inject a serialized PHP object into a post's custom meta field and trigger arbitrary code execution by exploiting a bundled POP gadget chain, resulting in remote code execution as the web server user.

Description :The Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Insecure Direct Object Reference / Authorization Bypass leading to Arbitrary Attachment Deletion in versions up to, and including, 1.8.11.1 via the profile avatar update flow. This is due to the save_avatar() function in Charitable_Profile_Form calling wp_delete_attachment() on an attachment ID read from the user's 'avatar' meta without validating that the attachment is owned by the user, combined with Charitable_Data_Processor::process_picture() returning the raw posted value when no file is uploaded, allowing the 'avatar' user meta to be poisoned with any attacker-chosen attachment ID. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary attachments from the Media Library by performing a two-request chain (first poisoning the stored avatar meta value with a target attachment ID, then triggering deletion via a normal avatar upload).

Description :On Tapo C520WS v2, restricted accounts (for example, hub users) are intended to execute only a limited set of low‑sensitivity operations. Due to a logic flaw in the device’s API authorization mechanism, an attacker can craft requests that leverage legitimate “method mapping” behavior to bypass whitelist restrictions, allowing restricted operations to be masked as permitted requests and executed. Successful exploitation may allow an attacker (with access to a restricted account) to execute unauthorized sensitive operations. Depending on the operation invoked, impact could include device resets, unintended configuration changes, or disruption of normal operation, leading to loss of availability and integrity of the device.
