Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject malicious script by submitting a crafted forum category description containing a double-quote character that breaks out of an HTML input value attribute. Attackers can exploit the HTMLPurifier configuration that preserves double-quotes to escape the attribute context and execute arbitrary script in the browser of users viewing the forum category.

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to post messages containing attacker-controlled iframes through the messenger's HTMLPurifier SafeIframe branch. Attackers can craft a message with a malicious iframe that is stored and automatically rendered to other channel members, enabling zero-click drive-by downloads and framed JavaScript execution in recipients' browsers.

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to persist unneutralized markup by submitting malicious values as two-dimensional POST arrays through the LDAP/person import flow, bypassing the paramsFilter() request parameter filter which failed to recurse into nested arrays. Attackers can inject arbitrary script code into a user profile that is later rendered to other users, resulting in execution of malicious scripts in victims' browsers.

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious scripts by submitting an unsanitized link address (adress) field that is echoed into an onclick event-handler attribute without neutralizing quotes. Attackers can store a crafted payload through the Links module that executes in the browser of any user viewing the links list, enabling session hijacking or further client-side compromise.

Omnispace Agora Project before 26.10.0 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious HTML attributes by manipulating the visioUrl parameter, which was not routed through the URL-sanitizing branch of the parameter filter and was urldecoded after filtering. Attackers can craft a malicious URL containing the visioUrl parameter with an attribute breakout payload to execute arbitrary JavaScript in the victim's browser pre-authentication, with the issue fixed in version 26.10.0 via changes to app/Common/Req.php.

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject HTML/script markup by uploading a poll-response attachment with a malicious filename that bypasses the paramFilter sanitization applied to $FILES. Attackers can submit a crafted filename that is stored and later rendered in components such as the dashboard controller (CtrlDashboard), executing arbitrary script in the browsers of users who view the affected page.

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious script by uploading a file with HTML/script markup embedded in its filename, which bypasses the paramFilter since uploaded-file names arrive through $FILES rather than $GET/$POST. Attackers can upload a file with a crafted name such as an SVG onload payload to have the unsanitized filename stored and later rendered to other users, resulting in script execution in their browsers.

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability that allows a regular, non-administrative member to create user accounts by invoking the user-edit action without a function-level authorization check. Attackers can exploit the missing editRight() enforcement in actionVueEditUser to create unauthorized user accounts, leading to privilege escalation.

Omnispace Agora Project before 26.10.0 contains a session fixation vulnerability that allows remote attackers to hijack authenticated sessions by planting a known session identifier in a victim's browser prior to login. Attackers can exploit the application's failure to regenerate the session id upon successful authentication to gain unauthorized access to the victim's authenticated session after they log in.

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability that allows a space administrator to assign users into spaces outside their authority because the spaceAffectList affectation was performed without verifying the caller's rights to the target space. Attackers can exploit the missing readRight() check in the import flow's join INSERT to break tenant isolation and manipulate user-space assignments across unauthorized spaces.

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in setAffectations() that allows authenticated attackers to insert access-right records for a caller-supplied target space without verifying the caller has rights to that space. Attackers can assign access affectations to spaces outside their own reach, breaking tenant isolation and granting unauthorized access to restricted spaces.

Omnispace Agora Project before 26.10.0 contains a second-order SQL injection vulnerability that allows authenticated attackers to inject malicious SQL via the idCategoryFilter parameter, which is persisted into the session and later concatenated into a SQL statement without parameterization. Attackers can store a malicious payload that executes when the filter is subsequently applied in app/Common/MdlCategory.php, leading to unauthorized database access or manipulation.

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in the MobileFileDownload route that allows unauthenticated attackers to download arbitrary files by computing an md5(filename) token instead of passing a proper authorization check. Attackers can guess or determine file names to generate the corresponding md5 token and retrieve protected files without authorization, leading to unauthorized information disclosure.

Omnispace Agora Project before 26.10.0 contains a path traversal vulnerability that allows attackers to write arbitrary files outside the intended temporary directory by supplying an unanchored tmpFolderName value in the upload destination path. Attackers can exploit this flaw, for example by setting tmpFolderName to a traversal sequence targeting the web root, to write attacker-controlled files and achieve remote code execution.

Omnispace Agora Project before 26.10.0 contains a SQL identifier injection vulnerability that allows a space administrator to escalate privileges by supplying caller-controlled agoraFields[] names as unvalidated SQL column identifiers during the user import flow. Attackers can inject privileged column names such as generalAdmin or use backtick-injection techniques to set administrative flags and escalate to general administrator privileges.

Omnispace Agora Project before 26.10.0 contains a vulnerability where the persistent remember-me token is stored verbatim server-side, making the stored value identical to the bearer credential held in the user's cookie. Attackers who gain access to the stored token, such as through database or backup disclosure, can replay the plaintext value to authenticate as the victim user without needing their password.

Omnispace Agora Project before 26.10.0 contains a predictable password-reset token vulnerability that allows unauthenticated attackers to take over user accounts by computing the reset token as sha1(login.password), a deterministic and reusable value. Attackers can derive or brute-force the reset token from known or guessed login and password combinations to forge valid password-reset requests and hijack arbitrary accounts.

Omnispace Agora Project before 26.10.0 contains an authentication bypass vulnerability that allows attackers possessing a user's stored bcrypt password hash to authenticate as that user without knowing the actual password, caused by the legacy AGORAPLOG/AGORAPPASS cookie mechanism treating the stored hash as a directly replayable bearer credential. Attackers can set the AGORAPLOG/AGORAPPASS cookies with a stolen password hash to impersonate any user, including administrators, and gain unauthorized access to the application.

Omnispace Agora Project before 26.10.0 contains an insecure randomness vulnerability that allows attackers to predict temporary or default account passwords generated by Txt::defaultPassword() using PHP's uniqid() function based on server time in microseconds. Attackers who observe or approximate the account creation time can compute the predictable password and take over the account before the legitimate user logs in.

Omnispace Agora Project before 26.10.0 contains a code injection vulnerability where unescaped, attacker-controlled values are written into the config.inc.php configuration file during installation through File::updateConfigFile() and DbInstall::dbControl(), combined with an SQL injection issue enabled by PDO::ATTREMULATEPREPARES supporting stacked queries. Attackers can exploit the SQL injection to re-trigger the installer and inject arbitrary PHP code into config.inc.php, achieving unauthenticated remote code execution on the underlying system.

File upload vulnerability in Omnispace Agora Project before 25.10 allowing attackers to execute code through the MSL engine of the Imagick library via crafted PDF file to the file upload and thumbnail functions.

File upload vulnerability in Omnispace Agora Project before 25.10 allowing authenticated, or under certain conditions also guest users, via the UploadTmpFile action.

Cross site scripting (XSS) vulnerability in Omnispace Agora Project before 25.10 allowing attackers to execute arbitrary code via the notify parameter of the file controller used to display errors.

Directory traversal vulnerability in Omnispace Agora Project before 25.10 allowing unauthenticated attackers to read files on the system via the misc controller and the ExternalGetFile action. Only files with an extension can be read.
