03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.50% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 43.1% of scored records. A rank, not a probability.
NVD base score
5.1 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

The is_uploaded_file() guard is hoisted to execute immediately after the basic size/error check and before any filesystem probe (file_exists, MIME detection, EXIF reading). If the tmp_name is empty or does not correspond to a genuine PHP upload, the method returns false early, preventing any filesystem interaction with an attacker-controlled path and eliminating the information oracle.
