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.","state":0,"publishedAt":"2026-10-15T16:26:16.585+00:00","modifiedAt":"2026-10-20T02:48:31.094+00:00","affected":[{"ecosystem":"Vendor product","name":"Lychee","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"LycheeOrg\",\n                    \"product\": \"Lychee\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.6.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-qcqq-p4pq-7r77","https://github.com/LycheeOrg/Lychee/pull/4449","https://github.com/LycheeOrg/Lychee/commit/fe07567c176bbdcda7b276bb6d664dfcd47a9b00","https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61610","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61610","identifiers":["CVE-2026-61610"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
