From 2.0.0-beta.4 to 2.0.0-beta.5, goshs leaks file-based ACL credentials through its public collaborator feed when the server is deployed without global basic auth. Requests to .goshs-protected folders are logged before authorization is enforced, and the collaborator websocket broadcasts raw request headers, including Authorization. An unauthenticated observer can capture a victim's folder-specific basic-auth header and replay it to read, upload, overwrite, and delete files inside the protected subtree. This vulnerability is fixed in 2.0.0-beta.6.","2026-04-21T20:17:00Z",{"cvss_v3.1":10,"cvss_v4.0":20},{"scope":11,"version":12,"baseScore":13,"attackVector":14,"baseSeverity":15,"vectorString":16,"integrityImpact":15,"userInteraction":17,"attackComplexity":18,"availabilityImpact":15,"privilegesRequired":19,"confidentialityImpact":15},"UNCHANGED","3.1",8.8,"NETWORK","HIGH","CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:R\u002FS:U\u002FC:H\u002FI:H\u002FA:H","REQUIRED","LOW","NONE",{"Safety":21,"version":22,"Recovery":21,"baseScore":23,"Automatable":21,"attackVector":14,"baseSeverity":15,"valueDensity":21,"vectorString":24,"exploitMaturity":21,"providerUrgency":21,"userInteraction":25,"attackComplexity":18,"attackRequirements":26,"privilegesRequired":19,"subIntegrityImpact":19,"vulnIntegrityImpact":15,"integrityRequirement":21,"modifiedAttackVector":21,"subAvailabilityImpact":19,"vulnAvailabilityImpact":15,"availabilityRequirement":21,"modifiedUserInteraction":21,"modifiedAttackComplexity":21,"subConfidentialityImpact":19,"vulnConfidentialityImpact":15,"confidentialityRequirement":21,"modifiedAttackRequirements":21,"modifiedPrivilegesRequired":21,"modifiedSubIntegrityImpact":21,"modifiedVulnIntegrityImpact":21,"vulnerabilityResponseEffort":21,"modifiedSubAvailabilityImpact":21,"modifiedVulnAvailabilityImpact":21,"modifiedSubConfidentialityImpact":21,"modifiedVulnConfidentialityImpact":21},"NOT_DEFINED","4.0",7.7,"CVSS:4.0\u002FAV:N\u002FAC:L\u002FAT:P\u002FPR:N\u002FUI:P\u002FVC:H\u002FVI:H\u002FVA:H\u002FSC:N\u002FSI:N\u002FSA:N\u002FE:X\u002FCR:X\u002FIR:X\u002FAR:X\u002FMAV:X\u002FMAC:X\u002FMAT:X\u002FMPR:X\u002FMUI:X\u002FMVC:X\u002FMVI:X\u002FMVA:X\u002FMSC:X\u002FMSI:X\u002FMSA:X\u002FS:X\u002FAU:X\u002FR:X\u002FV:X\u002FRE:X\u002FU:X","PASSIVE","PRESENT",true,[29],"CWE-200",[31,32,33,34],"cpe:2.3:a:goshs:goshs:2.0.0:beta4:*:*:*:go:*:*","cpe:2.3:a:goshs:goshs:2.0.0:beta5:*:*:*:go:*:*","cpe:2.3:a:patrickhener:goshs:*:*:*:*:*:*:*:*","cpe:2.3:a:patrickhener:goshs:2.0.0-beta.5:*:*:*:*:*:*:*",[36,37],"Goshs Goshs","Patrickhener Goshs",[39,40,41],"https:\u002F\u002Fgithub.com\u002Fpatrickhener\u002Fgoshs\u002Fsecurity\u002Fadvisories\u002FGHSA-7h3j-592v-jcrp","https:\u002F\u002Fnvd.nist.gov\u002Fvuln\u002Fdetail\u002FCVE-2026-40885","https:\u002F\u002Fgithub.com\u002Fpatrickhener\u002Fgoshs",0.74,0.00311,0.23723,false,null,{"timestamp":48,"automatable":49,"tech_impact":50,"exploitation":51,"cisa_decision":52,"cisa_remediation_timeline":56},"2026-04-21T20:05:21.029819Z","no","total","poc",{"vector":53,"decision":54,"priority":55},"CISAv1\u002FE:P\u002FA:N\u002FT:T\u002FM:H\u002F2026-10-25T19:01:50.677286\u002F","attend","medium","14D",[58],{"name":59,"source":60,"tactics":61,"technique_id":63},"Exploit Public-Facing Application","attack_vector",[62],"initial-access","T1190",[65],{"link":39}]
