02 Description

Versions of the package uplot before 1.6.31 are vulnerable to Prototype Pollution via the uplot.assign function due to missing check if the attribute resolves to the object prototype.

03 Exploitation and scoring

Exploitation
Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
SSVC decision
  • ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • 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
0.71% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 52.9% of scored records. A rank, not a probability.
NVD base score
7.8 (CVSS v4.0), scored by the NVD independently of the CNA.

NVD analysis status
Deferred. NVD last modified this record on 2026-08-10.
Red Hat severity
Important. Red Hat's rating for its own products, not a CVSS rating.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
