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 obtain sensitive information due to improperly controlled modification of object attributes. A user-supplied value could change an access-related setting that should be controlled by the system, which could expose sensitive information.

———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 execute arbitrary code due to improperly controlled modification of object attributes. A user could set a field that should only be controlled by the system, which could lead to code execution.10hCVE-2026-1220536.5 MED—
——0The Symfony Serializer component ObjectNormalizer treats any attribute name containing . (and, from Symfony 6.4, [) as a writable property path, allowing untrusted input to modify properties of nested objects and bypass their #[Ignore] metadata attribute in Symfony versions 5.4.41 prior to 5.4.56, 6.4.9 prior to 6.4.50, 7.0.9 prior to 7.1.0, 7.1.2 prior to 7.4.23, and 8.x prior to 8.1.11.
ObjectNormalizer::isAllowedAttribute() accepts such names, and setAttributeValue() hands the name straight to PropertyAccessor::setValue(), which parses it as a property path and traverses into the nested object. A payload key such as customer.admin writes to $order->customer->admin. The #[Ignore] metadata attribute is only consulted when the nested object is denormalized in its own right, never when it is reached through a path. #[Groups] restrictions are not bypassed: the path is only accepted when no groups are passed in the context, and then groups restrict nothing. When the root class carries neither #[Ignore] nor #[Groups], no allowlist applies and every key of the payload is let through. Because PropertyAccessor also resolves a path segment against public methods, a segment matching a public method name invokes that method with the attacker’s value.Applications that bind untrusted input to objects are affected, including controllers using #[MapRequestPayload] or #[MapQueryString], whose default normalizer is ObjectNormalizer. With OBJECT_TO_POPULATE, as used for partial updates, the traversal reaches an already hydrated entity graph, and the modified field may be persisted.
The fix accepts a property path only when the class metadata declares an attribute of that exact name. Declared paths keep working unchanged, and a path in the payload with no matching declaration is ignored.18hCVE-2026-1234908.8 HIG—
——0Craft CMS from 5.8.17 before 5.11.2 contains a privilege escalation vulnerability because getOwners() applies caller criteria without cleansing the query configuration. Authenticated control panel users can invoke attacker-selected static PHP callables via crafted criteria to promote every account to administrator.20hCVE-2026-1232949.6 CRI—

——7SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the V8 write path checks that a field exists but does not enforce api-visible or sensitive metadata that hides the same field on reads. The affected flow begins at PATCH /Api/V8/module and uses user_hash, external_auth_only, api-visible: false, and sensitive: true to carry attacker-controlled data or authorization state into the security-sensitive operation. An authenticated user can mass-assign internal authentication fields, modify password hashes or external-authentication flags, and persist unauthorized account access. This issue is fixed in versions 7.15.2 and 8.10.2.2dCVE-2026-1204488.1 HIG30.1%
——9DoraCMS through 3.1.0 contains a mass assignment vulnerability in the PUT /api/v1/user/api-keys/:id endpoint that allows authenticated low-privileged users to rebind their API key to another user's account. Attackers can set the userId field on their own key to a victim's id, then act as that victim to modify profiles and publish or delete content.5d
