03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- 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
- 0.29% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 21.9% of scored records. A rank, not a probability.
- NVD base score
- 6.5 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector

- NVD analysis status
- Analyzed. NVD last modified this record on 2026-07-23.
- Red Hat severity
- Moderate. 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.

Rust ProjectCargo1.0.0 to < 1.96.0— SRC: CNA
Rust 1.96.0, to be released on May 28th, 2026, will update Cargo to
reject extracting *any* symlink within crate tarballs, regardless of
whether they come from crates.io (which already forbids them) or
third-party registries. Note that Cargo never added symlinks when
running `cargo package` or `cargo publish`, so the impact of this should be
minimal.
