Summary
The CakeResponse::download() method in lib/Cake/Network/CakeResponse.php constructs a Content-Disposition header by directly interpolating a caller-supplied filename into a quoted-string value without sanitization. Two distinct injection vectors exist: C0 control characters (CR/LF) cause PHP to drop the entire header, leading to inline rendering and stored XSS; a double-quote character terminates the quoted-string early, allowing injection of additional Content-Disposition parameters.
Risk Assessment
An authenticated user can store a malicious filename (e.g., in MISP attributes), and any other authenticated user viewing the affected page may execute arbitrary HTML/JavaScript in the application context. This can lead to session hijacking, data exfiltration, and unauthorized actions.
Recommendation
Apply the vendor-provided patch that sanitizes the filename before placing it in the Content-Disposition header. Additionally, consider validating filenames at the application level to reject control characters and quotes.
Other vulnerabilities in CakePHP
See all- CVE-2016-4793High
The clientIp function in CakePHP 3.2.4 and earlier allows remote attackers to spoof their IP via the CLIENT-IP HTTP header.
- CVE-2015-8379High
CakePHP versions 2.x and 3.x before 3.1.5 may allow remote attackers to bypass the CSRF protection mechanism via the _method parameter.
- CVE-2026-79752Critical
In CakePHP, the FunctionsBuilder methods (cast, extract, datePart, dateAdd) allow SQL injection by improperly handling user-controlled input. Untrusted data is incorporated into SQL syntax without proper escaping, potentially enabling attackers to execute arbitrary queries.
- CVE-2026-77635Critical
CakePHP is a rapid development framework for PHP. Prior to versions 5.1.10, 5.2.15, and 5.3.7, FunctionsBuilder::jsonValue() with PostgresDriver is vulnerable to SQL injection when user-controlled data is supplied to the jsonPath parameter.
- CVE-2026-119419High
CakePHP through 5.4.3 contains an sql injection vulnerability that allows attackers to inject SQL by supplying unvalidated collation values to StringExpression and IdentifierExpression. Attackers controlling a collation name passed to the constructor or setCollation() can append SQL after the unquoted COLLATE clause, affecting every database driver within the connection's privileges.
- CVE-2026-119418High
CakePHP through 5.4.3 contains an sql injection vulnerability that allows attackers to inject SQL by supplying unvalidated frame offsets and directions to WindowExpression::range() and frame(). Attackers can pass crafted values through applications forwarding user input into the OVER clause to execute SQL with the database connection's privileges.
- CVE-2026-119417Low
CakePHP 4.5.12, 4.6.5, 5.1.8 through 5.1.10, 5.2.14 through 5.2.15, 5.3.7, and 5.4.0 through 5.4.3 contain an email header injection vulnerability because SmtpTransport and MailTransport strip only CRLF pairs from header values, an incomplete fix for CVE-2026-77634. Attackers controlling custom headers set via Message::setHeaders() or Message::addHeaders() can insert a bare CR or LF to inject headers like Bcc, redirecting or altering outgoing mail.
- CVE-2026-119416Medium
CakePHP through 5.4.3 contains an improper cookie domain validation vulnerability in the Http Client CookieCollection that allows malicious servers to receive and plant cookies by abusing unanchored suffix matching. Attackers controlling a host such as one ending in a victim domain suffix, or sending Set-Cookie Domain values for unrelated hosts, can steal session cookies or inject cookies into shared client cookie jars.
- CVE-2026-119415Low
CakePHP through 5.4.3 contains a header injection vulnerability in FormDataPart that allows attackers to inject MIME part headers via unsanitized Content-Type and Content-ID values. Attackers can supply CR/LF sequences in attachment MIME types or Content-IDs passed to Message::setAttachments() or HTTP client multipart data to add arbitrary headers or content.
- CVE-2026-77634High
CakePHP is a rapid development framework for PHP. Prior to versions 4.5.12, 4.6.5, 5.1.8, 5.2.14, and 5.3.7 on their respective release lines, custom mail headers added with Message::setHeaders() or Message::addHeaders() do not have CRLF bytes removed, allowing header injection when user-controlled data is used in message headers.
Original NVD description (English source)
The CakeResponse::download() method in lib/Cake/Network/CakeResponse.php constructs a Content-Disposition header by directly interpolating a caller-supplied filename into a quoted-string value without sanitization. Two distinct injection vectors exist in the unpatched code. First, if the filename contains C0 control characters (CR or LF), PHP refuses to emit the entire Content-Disposition header, silently dropping the attachment disposition. The response body is then served with its own Content-Type (for example text/html for an .html attachment) and renders inline in the browser on the application origin, creating a stored cross-site scripting condition. The commit message notes this is reachable even when the download_attachments_on_load setting is enabled, meaning a victim merely needs to view a page that triggers the download. Second, a double-quote character in the filename terminates the quoted-string value early, permitting injection of additional Content-Disposition parameters. The affected code path covers all callers of CakeResponse::download(), including attribute downloads, proposal downloads, and restSearch exports. An authenticated user who can create or upload an attachment with a crafted filename (for example through MISP attribute naming or proposal attachment naming) can store the malicious filename. When any other authenticated user views the affected page, the unsanitized filename is reflected into the HTTP response header, resulting in header manipulation and potential execution of arbitrary HTML or JavaScript in the context of the application origin. The security impact is equivalent to a stored cross-site scripting vulnerability, allowing session hijacking, data exfiltration, and unauthorized actions on behalf of the victim.
