Answer in brief
CVE-2023-26369 records a High severity vulnerability in [Google Project Zero] Adobe Acrobat DC OOBW 0-day actively exploited in the wild. The current sources mark it as known exploited. The current feed maps Adobe/Acrobat Reader (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
