description

Photolia versions through 1.0.3 are affected by an unauthenticated PHP object injection flaw. An unauthenticated attacker may be able to trigger PHP object injection; the advisory does not provide further conditions or impact details.

mitigation

Update to a vendor release later than 1.0.3 if one is available and confirmed to address this issue. Until then, restrict public access to affected Photolia installations and apply vendor-provided guidance.
