CVE-2026-89321

Eclipse OpenVSX is vulnerable to a disk exhaustion issue in its WebResourceService . When a VSIX is first requested via the unpkg endpoint, the service opens a zip entry with ZipFile.getInputStream() and passes the decompressed stream to Files.copy() without counting bytes written. The resulting ...

tornado: Tornado: Denial of Service via uncontrolled gzip decompression memory consumption

A flaw was found in Tornado, a Python web framework and asynchronous networking library. Its gzip decompression routines process data in limited-size chunks but do not enforce an overall limit on the total accumulated decompressed data. This vulnerability allows a malicious server to consume...
