CVE-2026-107213: Excelize: Nil-pointer dereference in GetSlicers when a worksheet has extLst present but no drawing element

HighCVSS 8.7 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: github.com/xuri/excelize/v2 (Go) 2.11.1-0.20260929015830-8ffeb07ec9a3.

Low priority for now. Upgrade to github.com/xuri/excelize/v2 (Go) 2.11.1-0.20260929015830-8ffeb07ec9a3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.9.0 to 2.11.0, GetSlicers checks for ExtLst but dereferences ws.Drawing without checking whether the independently optional drawing element exists. File.GetSlicers reads ws.Drawing.RID after seeing a worksheet extLst element even when the independently optional worksheet drawing element is absent. When a crafted worksheet contains an extLst element without a drawing element and the application calls GetSlicers, the nil ws.Drawing pointer is dereferenced while resolving the drawing relationship, allowing an attacker to panic and terminate an unprotected process. No fixed version is available as of this review.
