The injected script is executed in the browsers of any user who views the affected content, leading to a stored cross‑site scripting condition. This weakness is classified as CWE‑352.
Affected Systems
The plugin Spolecznosciowa 6 PL 2013, provided by szajenw, is vulnerable in all released versions through 2.0.6. Any WordPress site running a version of this plugin within that range faces the risk.
Risk and Exploitability
With a CVSS score of 7.1, the flaw carries a high severity assessment. Its EPSS score is below 1 percent, indicating a low but non‑zero likelihood that automated exploitation attempts are in use. The vulnerability is not yet listed in the CISA KEV catalog.
