Release Notes
  • v1.20.19 (2026-07-27) fixed an FTP-server vuln (upload outside defined volumes)
  • v1.20.17 (2026-07-06) fixed a vuln when a volume has both filekeys and dirkeys enabled
  • v1.20.17 (2026-07-06) introduced csp nonces, possibly breaking some javascript-based plugins πŸ§ͺ new features
  • #1602 custom thumbnail extractors; docs/example (thx @kamaeff!) 18648050 dbc6df81
  • #1604 u2c: password can be provided in env-var U2C_PW (thx @shermanhlc!) 47297475
  • wopi: option --wopi-accs to limit who's able to use the feature 78a4ee49
    • also fixes wopi on servers where user does not have read/write-access to root volume
    • also restricts the token to just that one file; good if the wopi-client is some cloud thing that shouldn't be trusted
  • #1591 wopi: use persistent file-ID which is necessary for real-time collab (thx @kamaeff!) efcf96e3
  • #1605 the lightbox can show svg images now 825f1c94

🩹 bugfixes

  • up2k: client could waste a little bandwidth while recovering from a network glitch 18791c57
  • if PRTY_CONFIG is set to a config-file that is also autodetected, then explain the misconfiguration instead of crashing like before 14e2d79b
  • wopi: fix session-timeout hint to clients (thx @kamaeff!) 92c3f32e
  • js: fix chance of duplicate prologue on very first page visit eeb399e3
  • js: fix panic on image dragdrop out of the browser window dcc0abd6 πŸ”§ other changes
  • up2k: client now detects when server or reverseproxy is incorrectly configured with an impractically small request-body-size-limit, crashing the website with an explanation how to fix it f19ef033
    • also allows setting the chunksize all the way down to 1 megabyte when absolutely necessary (bad idea, slow)
  • new option --allow-svg-js if you really want that 566de65f
  • shares: harden single-file shares some more 21c2c728 9ff6a71a
    • just removing footguns (motivated by a bug-report that was a false-positive)
  • copyparty.exe: upgrade to python 3.14.7 from 3.13.14 8b6e8972
    • larger and slightly faster (compensated for the size bloat by making the text-image-generator more shitty) 🌠 fun facts
  • the thumbex example is also a cool example how relevant the "pseudo" in PRNG can be; with random.randrange instead of os.urandom, first run followed by restarting copyparty and another run...heh
