CVE-2026-1113885.4 MED—
———Frappe Framework before 15.120.0 and 16.x before 16.33.0 does not enforce the per-user restrict_ip allowlist for non-session authentication methods, including API key, OAuth, and header-based authentication. Attackers holding valid credentials of these types can authenticate from IP addresses outside the allowlist, defeating the configured network-based access restrictions.7hCVE-2026-61610——
——0Lychee is a free, open-source photo-management tool. Prior to 7.6.1, when photos_star_visibility is set to anonymous, POST /api/v2/Photo::highlight can fetch and modify a photo without confirming that the caller can see it. BaseApiRequest::validateResolved() invokes SetPhotosHighlightedRequest::processValidatedValues() before authorization, and PhotoPolicy::canHighlight() returns true for anonymous callers without a canSee check. An unauthenticated attacker who can guess photo identifiers can distinguish existing private photos through differing success and not-found responses and can change their is_highlighted state, including for photos in private or password-protected albums. The issue is limited to installations using the non-default anonymous star-visibility setting. This issue is fixed in version 7.6.1.13hCVE-2026-97037.1 HIG—
——0Grafana's data source proxy did not apply role-based access control to write requests forwarded to Loki data sources. A user holding only the Viewer role on an affected Grafana instance could send POST, PUT and DELETE requests through the proxy to the Loki rules API (/loki/api/v1/rules), allowing them to create, modify and delete Loki alerting rules. Because those rules are stored by Loki rather than by Grafana, the change took effect for every user of that Loki data source, not only for the Viewer who made the request.
Exploitation requires an authenticated Viewer account on the Grafana instance and a configured Loki data source; no other privileges are needed. Both Grafana OSS and Grafana Enterprise are affected. The defect is in Grafana's data source proxy; Loki itself is not vulnerable and does not need to be patched.19hCVE-2026-951805.5 MED—
——0An issue in Justson agentweb-core v5.1.6-androidx and earlier allows a local attacker to obtain sensitive information and launch non-exported host application components via incorrect access control in the handling of intent:// URLS in DefaultWebClient16hCVE-2026-1060316.5 MED2.7%
——1The Spin Wheel WordPress plugin before 2.2.1 does not verify that a visitor actually performed a legitimate spin before returning and consuming a configured prize coupon, allowing unauthenticated users to disclose and drain the stored coupon codes of any campaign, including unpublished ones.19hCVE-2026-107795—12.5%
——4Omada Controller's MSP and OpenAPI certificate/private-key management APIs do not properly enforce administrative authorization, allowing an authenticated user to perform privileged certificate management operations.
Successful exploitation may allow a low-privileged authenticated user to upload or delete the controller's TLS certificate or private key, potentially disrupting secure management access.6h
