The Optimole WordPress plugin before 4.2.12 does not properly escape a user supplied value before using it to build an image tag attribute, allowing unauthenticated users to inject arbitrary attributes into pages served to every visitor, which leads to Stored Cross-Site Scripting.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | ||||||
